would TB staff ban me? ...if I send users messages that:
I'm a GM and need user's password to solve a case and other like that. Messages
that seem like scam but they are not, because I'm just messing around, not seriously trying to scam them.

I wouldn't even check the messages, if I log in the "stolen" account... =)

Would already be impersonating staff and isn't a good thing to do. I don't know if you can get infrcated for it though.

Would be like phishing. Generally asking for passwords isn't a good thing to do and I think you can get infracted for that.

Also, telling everyone that you are doing it isn't a smart thing to do either...

So yea, you would most likely get banned for it, no matter what you wanted to do with it.

No, as said above, it consumes both impersonating and phising.
And, smart users can know because your name is not colored and it has no % etc thing.....

Joker, names dont have % or ~ on forum. But yeah mark even If you were joking you'd be banned for like said above phishing. Do that is like trying to scam someone and just say I'm joking

What I mean is the ingame mark, you know....
I don't know much about GM ingame....

You will be banned. Dont do it.
