We take security vulnerabilities very seriously and work hard to provide a secure online experience for our users. If you believe you have discovered a security issue that affects many users, please report it to us so we can investigate and correct the problem.

Don't abuse other users when testing. You can use your own account or create sockpuppet accounts, but do not test or demonstrate your theories on (or at the expense of) your unsuspecting peers.

Choose "Other" as the type and include the words "Security Vulnerability". Be as detailed as you can in the steps required to reproduce the error. Please do not post serious security issues publicly on a meta site or elsewhere.

We are extremely grateful to members of the security research community who have reported serious security vulnerabilities to us directly. While we cannot always reveal what the vulnerability was, we do want to recognize their contributions publicly.
