Yeah, I wish there was a way to delete a post with out deleting it to preserve comments.
Maybe an “abandon” feature. It removes your user name from public view and does a simple find and replace to remove your name in the comments. The post can live on, but now you have nothing to do with it. The user would have a “abandoned post” counter, this so we know if a user is constantly abandoning posts and can block them. Or put a hard cap, more than 2 a month = banned from posting until mod appeal. Posts with 0 comments face no penalty and are deleted.
Someone still needs to be able reference to the original poster for modding and blocking purposes.
Worst is when they copy the click bait title, so the comments are full of people raging about something like “Lemmy now has a premium cost”, without realizing it’s bull shit.
