The comment is:
1) Usually worthless. "OMG, that's great!" is not as complimentary as they poster believes it to be, and only serves to waste the time of the original poster.
2) Not well thought out. The comment is usually quick, and does not justify itself. No reason is given as to why the user feels the way he / she does about said topic, image, story, etc.
3) Part of a mob mentality. Piranhas don't work alone, unlike most spammers. Their posts are usually followed by a swarm of like-minded posts, fueling the useless flood of empty comments.
NOTE: These types of comments are usually most prevelant on a forum centered around skills development. (Art sites, writing boards, game modification boards, etc.) Where a person skilled in whatever the forum centers on is easily attacked by piranhas and his / her post is quickly devoured.
