There's this user on tumblr named zamii070 who does Steven Universe fanart. A lot of other people on tumblr created blogs bashing her and accusing her of stuff like fatshaming because her Rose Quartz wasn't overweight enough, or racism because she drew Garnet without an afro (at one point there were 43 blogs about her).
She attempted suicide and was hospitalized for treatment.
SU cocreater Ian Jones-Quartey tweeted and then deleted this after backlash.
He then tweeted this.
@ianjq I have listened to concerns and I agree, my earlier statement was vague and reductive. Thank you to everyone who made me aware.— ian jq (@ianjq) October 28, 2015
