It's an instance that crossposts posts from Reddit, except it also makes a new user for each Reddit account it came from. So if /u/hello123 made a post, it makes that post under a new account called hello123. That makes it impossible to block posting bots.

Not only that, it makes posts look like they're posted by real people, with many question and text posts being copied as well. I was very confused as to what these posts were until I realized they're crossposts.

Examples:

I strongly believe Lemmy isn't the place for mirroring content from other websites. You can host your own alternate Reddit frontend like LibReddit, there's no reason to spam the posts to everyone using Lemmy just because 5 people asked for it. Not to mention there are already enough instances mirroring posts, this is getting obnoxious.

Yes, but this also blocks helpful bots, for example link converters. I'd like to block the x-post spam but keep the utility from other bots.

Yeah, understandable. On Lemmy World we defederate with those kind of instances because we know most of our users don't want that stuff.

Luckily the next version of Lemmy is around the corner and then you should be able to block those instances yourself.
