Yes brizz, I haven't heard many cases where Epic is banning individual keys from cheaters. UTAN global bans is the enemy, that's the whole reason DD is doing it. They feel the same as many here, that UTAN shouldn't be judge/jury/executioner, with their no tollerance attitudes towards cheating. So, they are finding ways to proove that the UTAN global ban system is flawed.
That is their point.
...and the problem is, even if admins wake up, and stop accepting global bans, there isn't exactly an easy way to filter that UTAN setting when browsing for servers, which would suck for anyone banned. They could just filter UTAN server by mutator, but then still get stuck with the ones that have it as a server actor if I'm not mistaken.
