Is folded comment useful?

Depends. Mostly, it'll hide comments from bots or people talking shit. Sometimes, it'll hide nice/harmless comments. Its weird.

I would say a folded comment could be useful related to something that is not safe for work, Not safe for children, but it's there is still there and readable.

Myself, I have spent a lot of time opening app the folded comments, because someone just decided to censor what I was saying, and then they downvoted what I was saying which then that becomes a big turn off very similar to what's going on and taking place on TikTok. It's kind of like the restraints are so tight. There seems to be no point in using a website who is going to penalize people that harshly and critically Over an opinion.
