What can I do? a player named b45 banned me from a game for no reasin, he was trolling me and mafiabank comes out of nowere and says I scamed cards but game was first to 3 he kicked me when it was 1-2 and I have to give him my items? what do I do im getting pissed.

Well, I'm not totally sure on this, but report it to a GM, by pming them.

I'm almost certain thats duel scamming if he kicks you before you win/lose. He probably didn't want you to win so he kicked you. If you don't have a screenshot than nothing will happen, you just need proof.

Hi, You weren't "scammed" because you didn't lose any items. We won't do anything about duels unless the /duel command was used.

And if it was first to three, and he never got 3, You don't have to give him anything.
