We had this issue since v1. There were the exact same rmt in the exact same areas for the entirety of v1's life with 7 lalafel cnj in starter gear and they would do nothing but spam leves for fleece or gather up large groups of sheep in coerthas and aoe them down (back when you could easily gather 20 mobs and aoe them in a move or two).

Nothing was done then either, no matter how many pics and reports were filed. I still have screenshots of my char standing in the middle of about 30 rmt around a node in la noscea. At that time I thought maybe SE was just undermanned, then once I heard they were deleting 90% if our gil I thought they let em keep farming so they could delete their gil and give them a big middle finger. Now I just think they don't take rmt and bots seriously, esp since we had the same issue in xi and some bots were around for literally years.
