EA has just released the latest Patch R21 after our very own admins 'Coyote and Chelski' caught a server crasher using the in-game chat. Recently our servers were under attack by certain individuals using the in-game chat to crash the servers. Although it was a group effort by our members, admins and some regular players, it was Coyote and Chelski that were able to catch him in the act. (For obvious reasons, we will leave out the specific details)
We provided the logs and the proof that in-game could be used to lag servers until they crashed and 3 days later EA responded by releasing patch R21.
Below are the patch details;

Changelog:
. There is a spam filter for text-chat: if someone sends 5 messages in 10 seconds, that player is muted for 60 seconds
. Text chat can be muted across the entire server
. Individual players can be promoted to "admin" (cannot be muted, spam filter does not apply) and "muted" (never allowed to text chat)
. All settings configurable via remote admin interface
. New textfile on-disk: textchatmoderationlist.txt [list of which players are admin & muted]
. Updated docs; publicly available at http://static.cdn.ea.com/dice/u/f/bfbc2 ... trator.zip

This is the only individual which we were able to capture details of.
