Tim says he’s pinpointed a flaw in Facebook’s security system that blocks users and computers from Facebook accounts — while also locking the accounts — if they are hit with too many failed logins or too many successful logins in too short of a time period. Facebook got back to Tim and says it’s aware of the issue and is working on a fix but doesn’t yet know when it will come.
A couple weeks ago I started having problems logging into Facebook. After emailing Facebook and not initially receiving a response I decided to troubleshoot myself. It turns out if you login a bunch of times within a short period of time (I don’t stay logged in) or if you login incorrectly one too many times Facebook not only locks your account but blocks your IP address. In my case they blocked an entire class c range of IPs. Some friends of mine are able to reproduce the issue. When I figured this out I sent a detailed email to Facebook and this is the response I received…
