It does depend when you got involved in social media. The fact that it has slowed down as a preferred platform definitely is the main reason that there isn't much drama. Back when LJ and forums were the primary place for fandom and more active, it definitely had its fair share.

The bots are its own problems, but Twitter definitely attracts its share of trolls and then there are just others who want to get angry for no reason. That's why the block/mute features exist.
