I wouldn't mind a per-minute rate limitation of anything - posts, comments, even voted, though a per-day one feels weird. Without that immediate feedback it is something that someone impacted by it would need to expend effort towards tracking, as if those additional votes were arguably somehow "bad" (otherwise why limit them at all? I mean for a normal human, even the top 2% of us, but obviously a superhuman bot level of activity would be something else entirely - and in fact in that case, could rather be handled by banning the account rather than merely limiting its contributions?) rather than contributions made to enliven a social media network that by most accounts (e.g. posts to various Fediverse communities) already lies more on the spectrum towards the fairly dead side, rather than being too active.

That said, I recognize that this is an incomplete, even arguably naive perspective since I am unaware of the technical hurdles being faced. Which raises difficult questions: if Lemmy is able to handle not only the current scale of tens of thousands of users but another order of magnitude or so beyond that, then is Piefed unable to do so? (Again, I do not know the answer here nor would be much help in finding one, just stating the questions that will arise from this, especially from the ML crowd looking for any excuse to criticize what they stubbornly see as solely a competitor rather than ally against corporate interests.)

Yeah, ya can't do it that way. That's how you follow Mastodon users from Mastodon.

You have to use the link Rimu shared to search for their instance, and the scroll through the people on the instance. This is inconvenient. It's supposed to be, for now. If you look for someone on a small instance with not many users, it will be easier.

That being said, I'm not seeing this particular guy's account from here either. I can only even see a handful of the 586 users on that particular instance. It may be a federation issue there.
