lol - oh please! Who doesn't lie about their age signing up here!
If dA was around when I was a teen, you had better believe I would lie about my age! I started drawing sexually explicit art at 15 and also ran one of the first yaoi websites in the US by the age of 16.
Also, I have banned from dA a few times, so I am keeping my self safe!
The legitimate artists don't lie about their age. And neither do I. Honestly, I'm just tired of seeing this under mature content filters that don't belong there (like poorly drawn shirtless men, although this is definitely drawn better than that).
This won't get you banned. It's just the word "fuck", and people use it and hear it enough every day that it doesn't matter. In fact, it took me a moment to realize what might make you think you needed a mature content filter in the first place. The most you need here is a mature content warning, not a full block. I'd imagine it would be quite annoying to those who have to make new accounts just to see it (or switch accounts if they already have an "older" one).
