Just for fun try this in game

Step 1) Do a 'Player Search' on your server for level 50 Thaumaturges and Archers (not
bard or black mages)
Step 2) 'View Search Info' on them to see how many have absolutely nothing else
leveled
Step 3) Pick a couple to look up on the lodestone and see if they have no fc, no gc, no
mounts and no minions
Step 4) Refresh the search results for about 10 minutes and see that they're all entering
into duties and coming back out every 2-3 minutes.

Guess what....in that 10 minutes you just found almost all the bots that the RMTs are using to farm gil on your server. Now can we get SE to have some real GMs monitor those dungeon runs and ban them the first time they teleport to a coffer/boss?

Edit:
INB4 - limited resources/manpower, just report them, maybe they aren't RMTs, hey you forgot to mention.. , if it's that easy, that's probably what SE does already
