If you don't want the info used against you, then don't say it. Especially don't say it in a public chatroom. A rule about PMs/personal IMs might have some grounds for existence even though I am still against it. A rule against remembering what was said in a chat that anyone can join is just kinda dumb. Its like saying you can't use what was posted on the forums.
