Under these types of videos? They more than likely are.I would agree if you mean that there is more shitposting than constructive discussion. However, if there is constructive discussion under the videos, then there is constructiveness regardless of the more numerous shitposting. After all, you can just ignore the shitposts or just flat out not scroll down if you don't want to see the comments.
