Libreddit does work, but not all instances of it do.

"Third reply downvotes" and other types of bullying done for absolutely no reason. Also, people misleading others to disgusting communities just to troll them, for example (and I am paraphrasing the names of the communities): "misspell the community's name to c/vercute instead of c/verycute and you accidentally get a sub full of gore" or "check out c/audioing, it's definitely not people doing a very disgusting thing to one of their body parts". I do, however, like the fact they're bringing the whole subreddit swap meme - for example: on Reddit we have had r/trees and r/marijuana_enthusiasts and I've seen that implemented into Lemmy instances already. I wouldn't get rid of that, I think there are some traditions that are neat and don't harm anybody.
It's your decision, and I hate Reddit and Spez ever since they decided to do the whole API thing, but personally, if I were to close my account, I wouldn't scramble all of my comments and posts. It makes it harder for people who still search for answers to questions on reddit to find what they're looking for. You aren't preserving valuable information with this, you're destroying it.
Mastodon and Firefish have been good alternatives for me, not to mention, they're part of the same fediverse as KBin
