I would assume because it's funny to see people's reactions to trolling. At least that's why I do it.
Though I try to do some minor/light trolling, just be annoying enough where people mostly go "Oh you" instead of actually getting super annoyed. And I only troll friends, not random people. >_>
Also I'm just curious TC, how often do you update your block list? Maybe a lot of those people you blocked are banned, typically people who like to troll just to be an asshole get into nonstop trouble lol
