No, I don't even know who they are banning. But not the big bot accounts. ALL the bot accounts on Chaos and Light are still active. I know who they are and none of them are being terminated. The numbers SE publish are just random accounts (probably the obvious gathering/leveling bots). The big accounts which get reported over and over are still active. They got temporary suspensions before so only god knows why they are not being monitored. Once the suspension is over they get right back to it.
It also doesn't matter if they setup new accounts or not. They are EASY to find once they get their thing going. All SE has to do is listen to people reporting these accounts and ban them again. Over and over. They are paying staff to do this. What's the problem? And why is is hard to prove anything? Bots are bots. The are predictable af. Not going into details because of obvious reasons.
SE could even install some software on your pc that could track certain things. Basically ALL the FPS games have some form of anti-cheat software built-in to their client you have to agree with. Seriously who cares? Only cheaters care. But no, SE respects privacy of offenders more than it respecs everyone else. You are not even allowed to call out bot accounts to spread awareness so more people can report them. Or not getting a reply after you report a bot account. Rather have them tell me "sorry but your report went straight into the trashcan because we don't care" than "because of privacy we can not reply blah blah and now you will never know if you wasted your time or not". Dealing with SE if just one big frustrating ordeal.
If they are too lazy/incompetent to deal with bots just tell us. Why is this topic a taboo? We all know it's there but no one talks about it.
PS: The ONLY reason botting in pvp ever got mentioned by Yoshi-P is because big streamer accounts exposed it and basically forced Yoshi-P to respond. Since no big content creators ever craft/sell anything (because boring content) this bot problem never gets exposure.
