You might as well block the entire lemmit.online instance since that is the main perpetrator of these cross posts.

I just checked - it has nearly 170,000 posts and only 3 users. At some point one has to question whether these posts are even wanted by the general community or if it has just become spam.

There is no to little engagement on these posts so they don’t bring anything new to discussion. And if the purpose is to enable users to view reddit content without actually going to reddit, there are sites which already exist for that purpose, e.g. libreddit.kavin.rocks.

I personally dislike when their posts flood my feed so I have blocked everything.

Block by user: the bot at lemmit online is the main offender.

Block the user. It should be just one bot doing it in the lemmit.online instance.

To do so just, from your instance website, click on his name and search for the block function.

EDIT: For future reference you can automagically hide all (properly flagged) bots’ posts toggling the “Show Bots” in your profile, but you will lose the useful ones too and the one not flagged will still appear.

There’s a giant number of posts, but only a small number of bots responsible for them. When I see a post like that, I click on the bot’s username, then click “block.” Didn’t have to do that very many times before those posts disappeared for me.

I agree. A few bigger updates here and there about what’s going on, but not constant reposts to where Lemmy starts looking like Reddit.

They seem to be posting them in their own communities, not spamming them everywhere else. Just don’t subscribe to those communities.

You can untick ‘Show bot accounts’ in lemmy settings.
