My parents don't care what I do now that I have my own computer, though they used to freak out on me because they thought I was giving very personal information to pedophiles and molesters because I frequented an xat chatbox - of course, I wasn't. They also are aware of dS but they never questioned me about it nor care - except once when someone posted a picture of a bouncy anime lady in a bikini in a random topic I browsed on their computer. That almost got me in trouble with my mom before I explained that it's a Spyro forum and I can't control what users post, heh.
But sorry to hear that Smolderbrawl.

I hope your parents lay off a bit and you can come back more frequently.
