🚨How to Protect Yourself From AI Scams 🚨

AI tools are getting better every month, and scammers are taking full advantage.

Criminals now use deepfakes, voice cloning, fake investment sites, and AI‑generated news to trick people into sending money or sharing sensitive information.

Scammers use AI to closely mimic human behavior to add credibility to their scams.

Here’s what to watch for and how to stay safe:

Key Red Flags

• Fake emergency calls using cloned voices claiming a family member is in trouble.
• Deepfake videos or photos that look real but are stitched together from online images.
• Romance scams built on AI‑generated profiles that feel "too perfect."
• Fake investment platforms promising guaranteed returns or "AI‑powered trading."
• AI‑generated news articles designed to make a scam look legitimate.
• Finfluencers pushing crypto or investment schemes without real credentials.

How to Protect Yourself

• Use a family password for emergencies so you can verify identity quickly.
• Slow down when a message or call demands urgent action.
• Independently verify investment opportunities before sending money.
• Enable two‑factor authentication and update passwords regularly.
• Be skeptical of unsolicited messages, even if they sound like someone you know.
• Check for fake accounts and inflated follower counts before trusting online advice.

Don't get scammed.

ABC! Always Be Cautious!

And in Other News...

• X Now Limits Free Accounts to 50 Posts a Day

X has quietly rolled out major posting limits for free accounts.

Unverified users are now capped at 50 original posts per day and 200 replies per day, a steep drop from the previous 2,400‑post daily limit.

Users hitting the new ceiling will see an error message telling them which limit they reached.

X hasn’t issued a formal announcement, but the updated Help Center page confirms the change.

The move appears aimed at reducing spam and bot activity, though longtime users say it may push more people off the platform.

To remove the cap, users must subscribe to X Premium, which starts at $3 per month for the Basic tier.

Here’s a Cool Tip:

If you rely on X for business or community engagement, monitor your daily activity.

You may hit the new limits faster than expected.

• Jury Tosses Elon Musk’s Lawsuit Against OpenAI

A federal jury in Oakland has dismissed Elon Musk’s lawsuit against OpenAI CEO Sam Altman, ruling that Musk waited too long to file his claims.

The verdict clears Altman, co-founder Greg Brockman, and Microsoft of all liability after a three‑week trial that drew intense attention across the tech world.

The case centered on Musk’s allegation that Altman and others breached their duty to OpenAI’s nonprofit roots when the company shifted to a for‑profit model.

The jury found the claims were barred by statute‑of‑limitations rules, effectively ending the dispute.

Musk’s legal team says it plans to appeal, arguing the decision hinged on “technical legal issues” rather than the merits.

OpenAI and Microsoft welcomed the outcome, saying the timeline of events had long been clear.

The verdict preserves OpenAI’s current structure, a nonprofit foundation overseeing its business operations, and leaves the company’s multibillion‑dollar valuation intact.

Grok Skills: Teach Grok Once and Reuse Your Expertise Forever

Grok Skills turn one-time instructions into reusable expertise that Grok remembers across conversations. You can now generate polished documents and automate workflows without repeating your preferences every time.

You explain exactly how you want a report formatted or a presentation structured, only to start from scratch in the next chat. 

That repetition wastes time and breaks consistency.

Grok Skills solve this by letting you teach Grok your preferences, formats, and workflows once. It then applies them reliably in future conversations.

Here’s a Cool Tip: Try Grok Skills.

Feature Explanation

Grok Skills add persistent expertise to Grok. 

Instead of re-explaining your style, structure, or process every session, you save it once and Grok recalls it automatically.

Built-in skills ship with every Grok account. 

These handle common productivity tasks: generating formatted Word documents (.docx), complete slide decks, structured spreadsheets, and polished PDFs. 

You can also upload existing files for Grok to restructure or expand.

Custom skills let you define your own expertise. 

Describe what you need in conversation, refine the output, then ask Grok to save it. 

Custom skills take priority over built-in ones. 

A dedicated Skill Creator helps you build more complex versions through guided conversation.

What You’ll Gain

• Save time by reusing custom formats and workflows without repeating instructions.
• Produce consistent, professional documents and presentations every time.
• Automate repetitive tasks like report generation or data structuring with your preferred approach.
• Build a growing library of personal skills tailored to your work or projects.

Step-by-Step Instructions

Here's how to do it.

Web (grok.com):



1. Go to grok.com.
2. Start a conversation with your Grok account.
3. Try a built-in skill by typing a clear request, for example: “Create a professional monthly budget tracker spreadsheet with income, expenses, and savings projections.”
4. Grok generates the file directly in the chat for download.
5. To create a custom skill, describe your preferred style or workflow in detail. Once the output matches what you want, say: “Save this as my ‘Client Reports’ skill so you remember the format for future requests.”
6. In later conversations, reference the skill naturally or just describe the task. Grok should apply your saved preferences.
7. In this example, I used the following prompt to create a monthly budget tracker:



• I want you to help me track my personal budget. Create a simple monthly budget spreadsheet with these sections: Income, Fixed Expenses, Variable Expenses, Savings Goals, and a summary at the top. Use clear formatting with totals and make it easy to read. Save this as my ‘Monthly Budget Skill’.

iPhone/iPad and Android:

1. The experience works the same way inside the Grok mobile apps. 
2. Open the app (iOS / Android), start a chat, and use the same prompting style for built-in or custom skills. File generation and downloads function within the conversation interface. 

Pros and Cons

Pros:

• Eliminates repetitive prompting and delivers consistent output quality.
• Produces production-ready files (Word, PowerPoint, Excel, PDF) styled to your standards.
• Custom skills override built-ins and work across separate conversations.
• No extra subscription required beyond a Grok account.
• Works well for both quick tasks and complex recurring workflows.

Cons:

• Brand new feature, so exact commands and interface details may evolve quickly.
• Requires a Grok account (free tier or higher).
• Currently limited to web, iOS, and Android.
• Perfecting complex custom skills can take a few refinement turns.
• Persistent memory means your skill definitions are stored with your account.

Feature Access

Grok Skills are live now for Grok users on grok.com, iOS, and Android. 

Built-in skills for documents, presentations, spreadsheets, and PDFs are included with every account. Custom skills are created through normal conversation or the Skill Creator. 

No separate subscription is required. Availability on other platforms is not confirmed at launch. 

Admin or enterprise controls may apply in some organizational settings.

Score

Criterion | Score (0–10) | Justification

Value | 9

Directly solves repetitive prompting and inconsistent outputs for frequent users, delivering meaningful time savings and better results.

Usability | 8

Natural conversational interface makes built-in skills immediate; custom skills require some refinement but feel approachable.

Wow Factor | 9

Persistent, user-taught expertise that carries across chats is a clever and practical leap forward for everyday AI use.

Total: 26/30 🌟 Excellent

A strong addition that makes Grok feel more like a true ongoing collaborator rather than a stateless chatbot.

Key Takeaways

Grok Skills let you invest a small amount of time upfront to create reusable expertise that Grok applies consistently. 

The built-in document and presentation tools combined with easy custom skill creation reduce friction and improve output quality across your daily interactions.

Check out these Cool Tips & Tricks.

• Start with Built-ins: Grok includes ready-made skills for documents and presentations. Simply ask in natural language for the file type and content you need.

• Save Custom Workflows: Teach Grok your exact formatting or process once, then preserve it. After a successful result, explicitly ask Grok to “save this as my [Name] skill.”

• Upload Examples: Share a sample file to quickly clone your preferred style. Upload a document or deck and instruct Grok to match its structure for future work.

• Name Skills Clearly: Give every custom skill a short, memorable name. This makes it easy for Grok (and you) to reference later in any conversation.

• Reference Skills Directly: Tell Grok which skill to use in new chats. Say “Apply my Client Reports skill to this data” for automatic formatting.

• Refine Through Feedback: Improve skills with targeted follow-up instructions. Give specific changes, then re-save the updated version.

• Use for Travel Planning: Create visually rich itineraries in presentation format. Describe destinations and preferences, generate the deck, and save the travel skill.

• Build Report Templates: Set up recurring analysis or summary formats for business use. Describe your ideal report structure once and reuse it monthly.

• Combine Skills Flexibly: Mix custom and built-in capabilities in one request. Ask Grok to use your saved style while leveraging its document generation tools.
