I built an internet billboard where companies and products get the spotlight. 👉 https://t.co/lU7hokM9Up
→ bid for #1
→ receive the traffic
→ stay there until someone outbids you
2,500 visitors and 1,120 clicks in the first 3 hours.

No ads. No API keys. No revenue sharing.

Just outbid your competitors to rank #1 and consider marketing done for today 🚀

[Sourav Sahana @pocdork]

@jonathan_wilke Problem is there are already many clones enough to confuse Google crawler, the following steps will establish https://t.co/jE8q3BA30d as the original, canonical source:

1. Add `/press` page — a dedicated, continuously updated page documenting https://t.co/jE8q3BA30d's coverage and success metrics.
2. Add `/blog` page — dated blog posts at https://t.co/hdfSMysn7C..., formalizing milestone updates currently shared informally via X and the About page.
3. Unique metadata — distinct titles and descriptions to differentiate https://t.co/jE8q3BA30d from clone sites.
4. Sitemap update — add /press and /blog/* to sitemap.xml for prompt indexing.

XSS using "xss.pdf" 👀

I’ve seen a lot of people successfully find XSS by uploading a malicious PDF that gets rendered inside a PDF viewer.

But there’s another angle people often miss: data exfiltration doesn’t always require JavaScript execution.

Depending on how the PDF viewer handles interactive PDF features, an attacker may be able to trick users into submitting sensitive information through a malicious prompt or form.

I put together the PDF PoC here:

Only test this on systems you own or have explicit authorization to assess.

Previously advertised on https://t.co/vOhlD5ITZm but no longer near the top?
I built https://t.co/0pqK3wxJlJ — a visibility marketplace for products, companies and individuals.
Launched two days ago:
→ 3,000+ visitors
→ 1,200 clicks
Start at $1. Rank globally and by category. See public click stats. Stay visible even after losing #1.
Early categories are still wide open 👀

I have a new idea that I'm going to build 💡

My Cursor agent is already working on an MVP plan.

This one will take a little longer than 3 hours though.

We just spent $16,000 to put Tutti at #1 on https://t.co/XF7fmPR7zw, and then we shot up into the X trends.

Have you thought about starting a campaign on Tutti, so more users can discover outbid

ok let us explain what just happened

- found https://t.co/uEJuT4nA0R
- it's a leaderboard where #1 is just whoever paid the most
- there is no product. it does nothing
- We bought #1 anyway for $12.6k
- Our intern said so

@jonathan_wilke what have you started
