When I'm in Limsa it's easy to report RMT bot.
But I found this place (Easter Thanalan), and these are clearly bots. They're constantly surrounded by npcs and just attack them over and over. Been at it for at least past 3 hours. (I noticed them for the first time right before going on learning party).

There's something shady going on in this part of the Thanalan, but I don't know what could I do about it.
