Whoever is in charge of that instance, STOP.
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:

https://lemm.ee/u/ItzMeRocket@alien.top
https://lemm.ee/u/CaptainCapp-n@alien.top
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.
Sorry, I meant it as a joke. Clearly it didn’t land.
To give you a serious answer, I think that the point is in understanding that “All” will always be an unfiltered firehose. If the issue is that you are running out of content in the communities you subscribe and that represent your interest, then we need to find ways to increase the amount of content here instead of chasing another fix by going to “All”.
In a way, this is exactly something that the mirrored content from fediverser could also help, and also another reason that I don’t understand why people complain about “spam”. The content from alien.top mirrored is ending up at a community that you subscribe, it is far more likely for that content to be interesting to you than a random post from a community that you do not subscribe.
Re: “finding out new communities to follow”: that’s also part of the Fediverser Project. The idea is to build a crowdsourced map of Lemmy communities to be recommended as the alternative to any given subreddit.
