A site security issue or security vulnerability is something like a hack or exploit on YouTube. It doesn’t include harassment or other violations of our Terms of Service.
If you think you've found a security issue or vulnerability on the YouTube site, tell us about it here. We need to know the exact URL of a sample page, if possible. We’d also appreciate it if you could include a detailed description of the issue. Be sure to use an email address where we can reach you if we need more information.
If you need to report harassment or other violations of our Terms of Use, visit our Safety Center.
