Hm, by and large bored rich people who decide they're bringers of death / somehow divine, yeah, it does seem like given the time of the first divine-kin and the Freakshow episode where Dandy proclaimed himself god, the two events may be correlated. Or I could be secretly donning a tinfoil hat, its easy to see correlation.
I decided to surf the tag and see how bad things have gone, and if any of them have likely "pulled a Mott". I thought it'd be pretty tame "I made that happen" stuff. I wasn't prepared.

This one speaks for itself in the sheer derangedness. You can just tell someone is refuting the poster, and he/she is just repeating "I'm a god I'm a god I'm a god" like a broken record.
