YSK: There is a bot spam posting reddit content, and blocking it will improve your experience sorting by All
Why YSK: This bot is constantly reposting reddit content to its own lemmy instance, lemmit.online. Most of it goes completely unnoticed and produces no discussion. If you like using All to find new communities, and sort by New, all you'll see is this bot. Its highest upvoted post has 40 upvotes and 0 comments, and it has over 6 thousand posts. You can filter the spam by going to the bot's profile and blocking it.
I blocked all the Reddit communities and instances. Lemmy needs to be it's own thing which require community involvement, not reposting shit posts from Reddit.
