Google AdSense

This site may show Google AdSense ads to support hosting. Ads do not change availability results. For issues with ads on usernamechecker.net only, email us with the page URL. We cannot change ads on other websites, and AdSense policy questions belong with Google’s AdSense help center.

GitHub

We can discuss bugs in how we check public GitHub usernames via the public API. We cannot reset GitHub passwords, unlock accounts, or access private repos. Use official GitHub support for account recovery — and never email us your GitHub password.

What to include

• Checker bugs: the handle, the platform, expected vs actual result (Exists / Doesn't exist).
• Privacy: the search URL or username page — no passwords.
• Abuse: the URL and a short description. Do not send malware samples.
• AdSense: page URL on usernamechecker.net and what you saw.

Response time

We aim to reply within two business days. Security reports are handled first.
