I don’t know if my screenshots of strange guildless groups in Stratholme in morning hours helped to swing the banhammer, but as of 17.06.2020 most of those players i’ve seen are gone from Stratholme.
You can check it out here => Stratholme Daily on Zandalar Tribe
Stratholme, which was literally overrun with 40+ guildless mages/druids/priests are almost empty now.
I’m not saying that everybody who wants at least some bots gone from their server should do what i did…But maybe it did help.
Also on a side note - how is population situation looking up right now, after the ban wave ?
