Well, generally most of the clients I have encountered will take the ; and split it to multiple commands although, you're point about splitting something into two commands if there is a ; would be a handy-dandy thing to have for users who don't have a client that can handle that...
As it stands, I got a strchr function running on each string that is getting sent to the database and has a value that may contain characters. If the check returns a postive value, it sends a message to the user that part of their file contains an illegal character and that they've been reported to the staff and it sends a query to a database stating that said user has a string in their file that is questionable.
I am tempted though to create an array of banned words and search through the database, but I don't know if I really want to go through with that...
