I know why Nadiya2000 got banned. That's because he was a spammer of requirements. In fact, I met him on
Pixiv.
When I commented on his work, he suddenly required me to draw himself. I drew, after that, he required me to draw him again and again. Since he was just a selfish, I guess he got banned here.
BTW does anybody want to remeet him on Pixiv and have an excellent time?
