When playing on community servers I never witnessed aim bots until now.
Uncletopia servers are okay...
there are funny inofficial game modes like:
x1000 multiplies all weapon stats by 1000
classwars one team is one class. for example medics vs scouts
randomizer, get a random weapon (for example Medigun as heavy)
jump training maps: solve pakours
grappling hooks on ctf (community maps like ctf orange)
100 players in one server
So: Community servers should be used more often by normal players, they offer diverse different maps and gamemodes and are a decentralized solution to the bot problem.
I just want more vanilla-like servers, as wacky gamemodes aren't really my thing. I mostly play on Uncletopia (as much because of bots as because of random crits), but there are times when this is either full or empty, so we need more.
