Daycare Attendant Sun

We've all had movies, shows, comics, video games, etc that we've loved. We've loved them so much, we joined a fandom on twitter, tumblr, deviantart, and more! But what happens when that fandom becomes too much, or too toxic, or you stop being friends with someone who used to like it with you? What fandoms have you been in, but aren't any longer? And why? #1 Backstreet Boys...need i say more? Report #2 Nintendo fandoms.. people in those fandoms acted weird..
