What do you think?
Well, I think, it takes more time comment using AI, and someone would only do that, if they are doing a lot of comments, to farm rewards. And as you said, normal human comments would not be always this big, so if someone is always leaving a big comment, then there is something to suspect.
Yeah there's a few people who write long comments but they were doing it way before AI was here.
But they will be very few and trust worthy as well.
