Plenty of people? I'd love for you to show me even 1 more than the person that started a thread about it yesterday that reported having their guilds disbanded with the last banwave...I'm willing to bet you can't find a single one. And you want to know why? Because there most likely was no investigation that went into the accounts that were banned during the banwave. The whole detection to ban process is most likely automated at this point and requires no interaction from a human being, other than them hitting the button to ban everyone.
I'm sure guilds are getting disbanded more than people realize on here, but those are for large gold sellers and serial botters. Your average botter is never going to have a guild bank removed, especially if you have more than just your characters in there. That may change in the future, but that is not how blizz is handling bans right now.
Your latest sentence has a serious issue; blizz is handling bans now differently to how they did in the past. Starting with 2nd? banwave, people were stripped of all the gold in their botting accounts. And if their chars were in botting guilds, all gold was removed and entire guilds were deleted.
After loggin in when the suspensions ended, those chars were guildless.
So, there's no evidence as to how Blizz is handling bans now. We'll find in 6 months or 18 months. What is known, is that their approach is changing.
About the "plenty of people"... Yep, sir, plenty. I did, and I did not create that thread. Loads of people here did. And the information is here in these forums, not only ( but also there!) in the ban reports, but also in threads created upon account retrieval of past banwaves.
I have spent (as many others) days, probably weeks, reading thread after thread upon years. I can recall that information; you apparently don't, and you estimate that the information is not real. Well, you are wrong.
Trying to find those threads is your duty if you intend to be well versed on the matter; please don't ask someone else to do that for you.
Edited to add: you spoke of an average botter. May I know what is that?May I guess you are referring to casual botters? Average for me could be 15 on the last 3 years. 200 for others. 1 for you. It's hard to create an average on that, only Bossland could.
