I was barely a teenager in 2003 and I sold certain pics and divx files of myself to guys on a weird IRC front-end thing called ComicChat by Microsoft. It made chat more visual and stuff. Look it up. It was really cool. Then I sent a rapidshare link.
Anyways, back to the point, back then before the card act of 2009 I remember having a PayPal first, then getting a credit card. I could buy stuff on ebay before I could cash it out to a bank account or even get a student credit card for years. This continued for a few years and I moved to another weird piece of software called Second Life. Eventually old people I knew no longer cared and I became an adult and it stopped all together. Had I been a little younger with modern systems I would have made bank like many girls now do.
I think it's a great actually. You are giving stuff that harms no one and making money. Everyone's happy. Just because some nobody Johnny Law has the gall to stick his nose in and dictate how I can and cannot live my life, fuck him. If you got it, use it because it doesn't last forever.
