This is currently being strictly applied in the chatroom. To avoid bans, I suggest chatroom users take great care not to let anyone else (site user or non site user) use their keyboard while they are logged in. If you wish to hand over to someone else, leave chat, log out and have them log in under their name and then rejoin chat, especially if you are a cam user who can be seen by chat ops.
(I've tried very hard to keep my personal opinions out of this post and keep this to facts that other users might find useful. I hope this post isn't interpreted as criticism of the rules, ops or site. This post is intended purely to draw people's attention to this rule and it's implications, so they can avoid breaking it.)
