Game, do you realize how much of an idiot you're being here?
He's asking you to come to his server because he has proof on there that the mod exists. If you refute that and simply think banning him instead is a good idea, then maybe you should rethink how you should run your administration system. You look like an starfish for those two simple points, and
this could have so easily been prevented entirely if you'd joined his server, or at least not banned him. You didn't have any real reason to ban him past the fact you didn't believe his mod existed, and there's no reason to claim that's enough to act on.
You're banned someone over a mod. Think about that.
Also, from what I'm understanding in this quote:
Again, I never said I wanted the mod in-game. I was busy hosting and didn't have the time to join. If Furdle here has any evidence or images of chat of me saying I wanted the mod, go ahead and post them.
you're refusing to join his server
now, even after you've stopped hosting.
Like, honestly, I'm not sure why you're refusing to do it now. Sure, it might have been understandable that you couldn't join because you had a server running and you didn't want to abandon your players at the time(and that's a bit of a stretch because you could have just stopped the server, looked, and then re-hosted it again if you'd wanted proof so badly), but refusing to do it now and just banning him is borderline handicapped.
