Original GitHub issue: https://github.com/laylavish/uBlockOrigin-HUGE-AI-Blocklist/issues/242

Bad URL: https://y-comblnator [.] com/apply
Domain: https://y-comblnator [.] com/

Reason for report:
This domain impersonates the legitimate Y Combinator site by replacing the “i” with an “l” in the URL to trick users. The site engages in spammy behavior, including mass pings and unsolicited issues on GitHub: https://github.com/ycombin/ator/issues/17.
(https://web.archive.org/web/20250923205627/https://github.com/ycombin/ator/issues/17)

Impersonation details:
• Misleading name and branding to appear as official Y Combinator communications.
• Promises $100M investment for a non-existent W2026 program.
• Asks users to verify wallets and make a refundable deposit, which is not part of YC’s official process.

Impact:
• Users may be tricked into providing sensitive information or making payments.
• Spam and unwanted notifications on GitHub repositories can disrupt legitimate developer activity.

Recommendation:
This domain should be flagged and blocked by security filters, domain registrars, and Safe Browsing services. Users should only apply via the official Y Combinator site: https://www.ycombinator [.] com/apply.

Additional notes:
• Official YC communications do not request wallet verification or deposits.
• This domain could potentially be used for phishing or financial scams.
• GitHub contributors should report spam activity via GitHub’s abuse reporting system.
• Security teams should monitor for similar “lookalike” domains that attempt to exploit brand trust.
