We would like to remind everyone to NEVER enter their password into the RuneScape chat. Not for ANY reason.
In an attempt to better protect our players' passwords, we've updated the game to prevent you from saying any sentence which contains your exact password. This is only a basic check, however, and it's still extremely unsafe to type your password into the chat, so please DON'T try it out to see! That would be foolish and extremely dangerous. For instance, you could still accidentally give away your password if you mistyped it, or if you typed it somewhere we don't filter yet (such as the forums). So please, please DON'T test this out - it's not worth the risk!
From now on, if you enter your exact password into the chat, the entire sentence will be blocked and you will receive the message:
"You appear to be telling someone your password - please don't!
If you are not, please change your password to something more obscure!"
(We block the entire sentence to avoid giving hints about your password from the context.)
Also, please remember it's still a very serious offence to ask/try to persuade another player to give you their password. This is a direct breach of Rule 3 and will not be tolerated.
