I keep it off because I don't care if it's mature content, I either like it or not. Nudity, blood, etc- doesn't bother me or affect whether or not I am drawn to a picture.
HOWEVER, I do get quite tired of all the borderline porno images of girls on here- not the tasteful nude ones, I'm fine with those, it's the one's where they LOOK like they belong on a porn site. It's annoying because it got deviantart banned at my school, and I use it a lot for art class to get my images from my gallery.

Before dA blocked the off option for minors I always had mine off. I'm pretty desensitized to a lot of stuff (Well, sexual things anyway. Violence still unnerves me a bit.).

As soon as I turn 18, I'll be switching it off.

I had it off most of the time I've been on DA but I got tired of sleazy boob pics and fetish stuff popping up every time I come on here. Too bad because there is some great nude work on here, unfortunately there's no filter for sleaze. Its not like there's nowhere online to find tactless boobie pics....

Waaaaaah you just reminded me that I've turned 18 and I can turn that off now! Thank you.

I have it on, but only because sometimes I check dA from work and I don't want to get fired for something out of my control. But once I get home I look at it anyway.

Off - i am old enough to decide by myself what i want to see.

IM TOO LEEDLE TO UNDERSTAND THE COMPLEXITIES OF BOOBIES :U

Off, art is art.

_{Sides' I have a lil' closet perv side to me....XD}

I have the filter on because I have a tendency to check my mail (DA included) in public areas.

Mature filter?!?!
Even if I was under 18 I would lie just to see boobies and pussies!!!!
After all, the internet is for porn!
