Hi there, I'd like to report a player by the username of pi99. Reason: He pretty much lied to me and made me have some very bad feeling when i trusted him on a trade. And he really really hurt my feelings by swearing at me and calling me mean words after he tricked me into this. I really wish you can ban him, because I don't want anyone else to feel this. And when I told him I reported him, he didn't feel guilty or scared at all, so I really wish that you can ban this player. Thank you. -Doggeepoison
Scamming is allowed unless it involves you getting scammed real money. Even if he did scam you real money no action would be taken because you have insufficient proof. If you are offended by him swearing at you simply do /ignore <player>.
The player most likely won't be banned unless what he/she did was very serious, but he/she will most likely be punished if you attach evidence like screenshots or videos.
I recommend you /ignore the player if it's bothering you this much. Other than that, you have no proof.
