Yeah, I really wish they add a delete comment and block user feature because there are many kids who spam hate comments just because they can. The worst part of having no mean to block rude people from commenting is that some other kids will copy them and ruin creator's experience.
It happened to me in 2016, even worse the haters lied to my fans that I infringe the copyrights when I didn't and many spammed the report button to get my comic banned and I got banned
If they had a block user feature this could've been prevented.
