I would say, only the larger servers/instances are at that risk (the costs need to come from somewhere). They’re not going to come and bother me for example. And if they did, I’m certainly not in it for the money. I’m running an instance I can afford to run. If it got too big I’d stop registrations.
Any group/individual that runs a server can be approached by, say Cambridge Analytica, just the same way Zuck or one of his C suite execs were.
