Just go to a few finance/stock forums and act like some newbie fool and say something like "I like Paypal a lot. I download all my porn at <File locker here> and always pay with Paypal. It's so much better than paying with Visa or Mastercard. More privacy. Those guys at <file locker here> even have women with donkeys!!! (Not that I want to see that crap) Anyway I have $20,000 in savings. how much would you all recommend I put in? I don't need the money to live on. Thanks."
Or tweet about them with something like this. It'll get their attention for sure.
More ideas:
1. Ask on yahoo answers if Paypal is anonymous and if anyone can trace the illegal porn you download at <flielocker> based on your paying with PAYPAL. We can be their worst nightmare for sure if we want to be.
2. Call up Paypal pretending to be a customer who paid for a subscription at <File locker> with Paypal and complain that there wasn't as much Donkey porn as you were told there would be and you would like to get a refund. Get "accidently" disconnected once they ask for your info (or actually purchase a subscription to make it more real). Somehow slip in that "Yeah, I even see child porn there on that filelocker but unfortunately they must have deleted all the Mexican babes with horses."
