Nothing we can do, you can report them - then, maybe, if you are extremely lucky, they will get removed in the monthly ban wave.
There are no GMs checking these things out anymore, as the manpower needed would not be… ‘cost effective’. So, they trust in automated systems to root out the worst of it.
We know it doesn’t work, heck - normally you wont see anything done for months, then Asmongold makes a video on it, and suddenly, an issue that has plagued us and been reported for all that time is fixed - within a week.
There just need to be a big enough stink about it to make it worth getting fixed.
Remember the Advertisement spam in LFG/tradechat? Yeah, they fixed it, but it took years and all the influencers were harping on about it daily. People just gave up fighting it. They quit WoW because of it. So much preasure had to be applied, before something was done.
The obvious Moonkin farm trains? Same story.
Dungeon bots? Flyhacking bots? Node farming bots? … hey, you report em every day for a year, they still there. Heck, I am scared to go back - the same names might still be there to this day. Luckily, after the influensers pointed it out, they got sharded away from our sight - you could still get time to time sharded in with them though… yep, still there, just hidden. Repeating the same pattern, over and over, 24/7… clear “player” behavior.
So… my point: There is nothing a regular player can do about it, but report, pray - and maybe do a twitch prime gift away so an influenser makes content about it.
Why it is as such? My best guess is lack of will from the top-end to do anything about it. Also, a economical insentive to keep them around.
Sub is a sub, after all. Look good on em Q calls. Hey - ban em monthly (or more rarely, if they are stopping), so you make sure the bot-owners made a profit - all so they will buy a new edition of WoW to do it all over again… both come out with quite a bit of money earned.
Just pure speculation of course. I would never say someone would let something go on, just because it is money to be made. I am just saying, it is a playfull thought in the back of my mind.
