Well, in response to the recent spamming attempts on here, I've added a new regular expressions-based banning system. This system will traverse the GET, POST, and COOKIE arrays, looking for matches to certain patterns which I have defined and will continue to update. Primarily, my goal is to block automated scripts from adding their content to the comments, which do not require authentication.
If you happen to see a message stating that you have been banned (which is highly unlikely), and you feel that it is wrong, let me know right away.
I apologize now if this causes any problems for anyone: That is not my intent.
