I was in a room and these two people were saying stiff about me so i told them to shut up and the admin. said i was rude and THEN kicked me out??
Not. Fair.
everytime i try to log into iSketch it says " Connection Refused! You are blocked from the game"
I don't know whats going on. I've never been blocked before.
Will it only last for a period of time?
Do i have to do something to get back in?
Will i never be able to play again?:cry:
Please answer my questions /
I would really appreciate it.

The best place to be to let your questions answered is info@isketch.net that is feedback of iSketch. They know best.
It is probably the short version you are telling here, and maybe you can tell the elaborated version in an email to feedback. They will read your email. We can only wonder what happened, heh.
Blocked means you are blocked from the game for a period of time. If doesn't indicate a period of time though. Keep trying, you will get back on, eventually.
