A large fandom I'm in ran a popular fanartist off Tumblr last month because having top/bottom preference in her ship meant she's homophobic, apparently. It's pretty common to get anon hate in this fandom but the sheer volume she was getting was awful. Then after she came back a couple weeks later, someone immediately started circulating another hate post about her.

It reminds me a bit of when Aja could run people off fandom (I'm still bitter over that one time with Hikaru no Go). But back then you had to be a BNF to make it take off, whereas now anyone can start a hatepost and it just needs to get picked up by a BNF blog and suddenly five thousand people all hate your guts. I live in fear of having one of my posts get big because the last couple of times, getting big = hate mail.
