Dunno. Where there are some eyeballs, there's some market for influence. Obviously someone is bothering, but as for how much money is being thrown at the fediverse at this moment, I would guess somewhere between "peanuts" and "small potatoes". On the other hand I imagine a bot trained here could be deployed elsewhere with little effort, similar to how a reddit bot can be deployed to lemmy with a little bit of rework, so maybe it's seen as a low-risk training ground. In any case I don't see it being a problem that gets less salient as the fediverse grows.
