In part, I think it's due to how colorful and easy to insert yourself into it these things are. There's a commonality in the way fans interact with these properties and how they've let themselves go off the rails.
It's probably also a factor of "these things got known for having weird fandoms, so the weirdos continue to gravitate towards it." If you've the beginnings of a weird hyper scat furry diaper fetish, you're probably gonna end up getting into Sonic before, like, TMNT or something. Every fandom has weirdos, but the ones that are more popular will have more and more known it is that there is a group of weirdos there, the more weirdos will show up looking for buddies.
