It bothered me bad when my kid started getting into it because of all of the bullying those folks get.
She’s a teenager and she’s having fun. She’s learned to draw and sew because of it. I haven’t seen anything even remotely worth my concern. They create characters and stories and just have fun. She’s learned to use 3D modeling software and serious art software. I got her a decent drawing tablet and she draws things for the kids who can’t draw. She’s developed some serious skill as a result of her interest in the stuff.
