I must stress Rule #3 here:
"3. We will not allow 'mature' content into the group if we think its too inappropriate."
Already I have had to remove numerous deviations that broke this rule and depicted the characters (mainly the female ones like Deb and Lola) in grossly sexualized ways. I also had to remove a few that represented various uncomfortable fetishes like inflation and giants, or whatever the name for that is. I was a bit disappointed that these sort of pics were accepted without regarding Rule #3. It might as well not have existed. The gore/violence hasn't been too bad, and some of it has been censored, which is good. I'm sure there's more pics that need to be removed, but I'll have to get to those later.
I would like to see this group be safe to look through without the uncomfortable factor. This show means a lot to me and I enjoy seeing people draw fanart and write fanfiction and all of that, but these sort of things are what makes part of the fandom unbearable and looking it up on dA risky. It's bad enough the Robotboy tag on tumblr suffers through the same thing, but at least my blacklist there keeps me from seeing the worst of it.
With that being said: NO MORE accepting of any art that involves any kind of fetish or any of the characters in gross, perverted, or situations that are very inappropriate. Tommy, Lola, and Gus are 10 year old kids and Robotboy and Robotgirl are also too pure and innocent to be depicted in such ways. There's also too much sexualization that it's sickening and gross to look at and needs to be stopped, as well. These people can find other groups to accept their perverted, disgusting, and fetish-fueled "art".
