Hey Isolated Due to recent people posting porn, and hugh images in the shoutbox I think you should disable image code in the shoutbox to prevent this from happening in the future.
I couldn't find a disable, but I made [img into a censor.
Also, enabled flood control. 20 secs for Members, 15 for Regulars.
It appears BBCode gets processed before censoring. This is another one of those things I wish I had FTP for, because isolated hasn't been around here lately.
