I was 15 so I spent it all on stupid shit :P I continued this into my early 20s.
Bitcoin wasn't around yet.
Tons of crazy stories for sure. Captchas weren't invented yet, no one really had any rate limits on login pages, inbox spam filters were easily bypassable, trojans like sub7 were just coming around, all kinds of wild fun back then. If you wanted to make money, there nothing was really stopping you.
Any other crazy stories from those times? You seemed to be ahead of the curve.
