It's fairly probable as I noticed groups of gladiator bots going around on multiple servers earlier today.
They don't teleport around like the usual gil farmers do, so the only thing that really gives them away is the fact that they form a conga line if they're together and mirror one another's movements perfectly.
It's a little concerning that they apparently have the entire MSQ routed out and are able to get through it without use of hacks, though it naturally involves getting carried through instances by actual players because it's not a "team" effort like it is with the gil farmers who operate in their own parties.
