Hi, I think you need to edit those screenshots to hide the names - apparently forum rules are *very* enforced about not 'naming and shaming' characters even if they are almost certainly bots....

But yes, I assume they're the "blinking in and out of existence while you try to have a conversation with the NPC" type? They'll be 'playing the MSQ' in that area currently and they will keep on warping back and forth between that NPC and whatever other quest objectives they need to interact with. I've had the same thing and I don't think there's much you can immediately do besides coming back later when they've moved elsewhere.

If they level up or do something that makes their name appear in the chat log, maybe you could try selecting it from there and using the 'report RMT' option? (Or maybe try /poke-ing one or something to get the "you poke Qwerty Uiop" text and see if you can work from there.)

(Also apparently three black mages and a white mage is the standard 'bot party' for this sort of thing, hence the crowd of black mages. I got their friend while I was trying to run my white mage quests and they kept appearing right on top of the questgiver.)
