Because I've had more than one person do this, so I guess the obvious needs to be stated:
Do NOT use a fanartist's comments section to rant about how much you hate the person who made a thing they enjoy. I really don't care that you hate Vivziepop, nor does the vast majority of the internet. I do, however, get extremely pissed off when you feel the need to express your hate in the comments section OF MY OWN FANART. This is a space specifically for fans, as if that wasn't clear enough. You have the entire rest of the internet to rant about artists you don't like.
Anyone who does this in my comments sections will get instablocked.
