@dfox , probably we need to find a way to stop reposts , may be having something like similar posts 😐

You can downvote a post and mark it as repost.

You already have this 😊 you can 'downvote' a post and pick 'Repost' as the reason. You'll also need to head over to your settings and switch on the option about hiding reposts. I don't think the OP has their score reduced when you do this, so don't worry about that
