Every single case has a proof. However, unless they're caught by the public eye, such as HunTinG, Casper, now Legend, among others that I've already banned, the list will remain anonymous; does more psychological damage that way. You silently hack, without warning you are silently banned.
The reason behind their ban? They hacked at some point today to the first day of 2018, without permission nor admin supervision. So if it applies to you, then congratulations, your days are numbered. This includes speed hacks, wall hacks, aimlock, health hacks and known/discovered distributors. That's all the public needs to know and will know from my end at least. The others have their own list, and their own methods and their banning plans for their own servers.
Now to give an idea of the magnitude, how many have I caught? Roughly 100 people, 1/4 of the community thus far and I haven't even finished my list yet, isn't that sad? Some are already banned in other servers, and are publicly known, I just haven't dealt with them yet. Some are whom I've silently watched and done nothing against for months, Legend is such an example.
It's a damn shame just how toxic this has gotten, but hey, be my guest. Free for all hacking? Free for all banning, simple as that.
