There's that weird place discussed by the other instance's admin here:

It’s a small nitherlandian instance that automated posting of christian testimonies (30k+, basically a youtube crawler by keywords, updated hourly) in one community and others are filled with conspiralogical content. Maybe they had their place somewhere before?
Haven’t seen a direct bigotry at a quick glance (closing my eyes on muslims finding christian Jesus-posts), but it looks like spreading conspiracies and serving as an ad for a cult. Is that against our rules? They sometime showed in my feed too. And they are an outright spam entity having 30k posts for like 50 users.
I think that's either a sectarian indocrination or someone being very ill in the head.
I vouch for defederating them and maybe contacting them if they need personal support.
It's exactly what some of youtubers would do a write up about a year after.
I think it is in the latest version.
Maybe, maybe. Some persons seeing this would test it.
It is sort-of in the next update. Users can "block" instances, what this means IIRC is that they will not see posts or communities from the blocked instance, however they will still see the blocked instances users posts on communities on other instances, as well as their comments on posts on other instances. This feature should work to block the spam you're talking about. We haven't upgraded to that new version on sh.itjust.works yet because it introduced a bug in the federation system that hasn't been fixed yet.
Lemmy Connect blocks both if you are a droid user.
