I'm a super administrator on Blackwatch's server, and Smooth's ban was justified, duping 50k bricks and then going "XD' about it is clearly something not tolerated.
We have idiots come in and join to stuff on the server too often, it's loving annoying.
It also appears that you cut off a lot of discussion in screenshot 3 and screenshot 4, what happened before Screenshot 2, explain in full detail please.
