I'm not gonna out the user since that would put this post in violation of one of the rules here, but it appears they've set up camp and created their own communities to botspam to. I DM'd the admin of their home instance but who knows if they'll see a problem with it.

Edit/Update: That spammer now appears to be banned on their home instance.

For me, it's the people that come here and feel the need to bring all of Reddit with them. Like, do they also bring their shitty exes and all their baggage on dates with their new SO?

And it's not like instances are largely (entirely?) volunteer run and rely on donations or admins footing the bill for hosting. Oh, wait. They are. 18,200+ posts (as of this comment) from a two month old account with the associated thumbnail images, each federated out to who knows how many other instances that store copies and local thumbnails is a pretty clear abuse of the platform. I'd also wager that the userbot in question isn't donating to their home instance, either.
