They banned allot of us who moved to VPSBoard by IP address, which is fairly easy to do with Nginx.
Now they moved LowEndTalk.com to Rackspace and enabled CloudFlare. The problem is that Vanilla Forums doesn't work well with CloudFlare (and that one module that exists for Vanilla to make CloudFlare work is broken), so all they see now when anyone logs in is their own IP address for each member.
It's one of the reasons why I took down LowEndTalk.in. Vanilla isn't very good software, that's it.
