ZestyI heard that the source code for the bots is open source and the bots have detection to find other bots ingame built in? That seems like its pretty easy to detect and ban tbh.
almost all modern cheats have this function built in (some choose to show it to customers and some only show it to cheat administrators) and it can't really be touched by anticheat easily. see: aimware "mod immunity", nullcore, etc
