I think the main issue is that Lemmy is a fraction of the size of Reddit. Most people probably assume they need to post the same content in different communities to increase visibility. However, Lemmy is so tiny that posting in one community is more than enough for everyone who would be interested in the topic to see it.

I think it’d be easiest to just find the largest version of a community and post there, ignoring all of the other communities.

Exactly! That entity is really fuckin irritating.

As far as I’m concerned, it is just spam.

More advanced filtering. There’s too much spam content, both human and bot made, that fills my feed. It’d be nice to be able to filter it with some rule system or regex or something. I don’t want to see the same person posting the same thing across identical communities in different instances back-to-back in my feed.
