And? People should be allowed to post them, deviantart or not. It's not my problem, you just want to force people to draw.
All memes and posts are welcome on Deviantart. They did not kill your family. And I admit I have my own stuff outside of this that I have never found funny or clever, but unlike you, I have never harassed anyone for years. So yeah, if you never wanted this, then you should've kept this to yourselves and went on other sites. All this fully convinced me that you think Deviantart is the internet. / In response to all of these:

Seriously, you don't get to decide what they can and can't post and where they can post them. If they want to post fill ins on Deviantart, let them. Don't like them? Either ignore them or kill yourself!
