In your account settings there is an option to show content by bots; unfortunately this only works if that account is marked as a bot.
For the bots I have found that are not marked, I’ve just been reporting and blocking them.
It took a few days but now I rarely see them anymore
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 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.
Okay, thank you! As long as I'm not the only one in the dark about this lol I haven't been on reddit since the start of the protests, so if I haven't seen it it's new to me 🤷♂️
