Trolling can be funny/hilarious every once in a while, but I still don't like it very much, despite laughing at it. It's mean. : (
You're probably thinking "But you troll a lot of members with ban threats!" but that's kind of different since I'm not especially aiming to irritate/intimidate people for my own amusement and more doing it in a light-hearted manner, so you could call it more of a "mean joke" or something.
By the way, Hika wasn't exclusively a troll. He did it sometimes, but I'm pretty sure 99% of the time, he was just posting his honest thoughts.
