I have no knowledge abt stuff like this whatsoever so I just hope the redditor pixiekatt521 has it right:

Believe it or not I consider this a sign that botting really is being countered. Do you know why you didn't see all these bots before? They were hacked to move under the map and instantly teleport from objective to objective. The fact that they are actually being seen outside of giant stacks suggests the scripts no longer work like they did. Yes, the amount of botting is still an issue, but all that's really changed is the size of the issue has been brought to the surface, literally. And now that they're in plain sight, they're much easier to see and recognize, and that means much easier for their activities to be recorded and taken down in the next ban wave (and before people say they don't ban bots because of the official report numbers, I want to respond that I doubt there are nearly 9k accounts shouting about rmt websites, and that most of the "rmt/prohibited activities" bans are probably these bots. The note for specifically bots is probably just for those that aren't banned for any other higher reason)
