'kay, read everything.. here's what you do.. drum roll please.
Ask your parents straight up whether they took the computer for the farmsville experience, or because they don't trust you not to love yourself too much (..and why exactly do we need a computer these days to do this? I sure didn't.)
If it's farmville, offer to build them there own gaming rig -give 'em a family discount
If it's the latter, offer to route your internet through their machine, so that they can log all of your internet activity. Once they see a log 300 pages long, they'll forgo actually reading them.. skim it once or twice, won't come across anything naughty (be smart, just DL the pron to yer phone or whatever if you're so inclined. I'm assuming here yer not so inclined..)
and trust is yours again.
btw, offering that the internet can be routed though their computer for monitoring will go a long way towards putting the trust their to start with.
Me thinks this the fairest solution to thouest parental problems, my young squire
