Aside from cred, there were a lot of like minded people and back then it was hard to find locals who were into computers/tech, so it was sort of a social network of sorts on IRC back then, I made real friends that I still keep in touch with today, so in a way it was a shared social activity.
One fun anecdote: When I was like 14, I got on a PBX 1800# call with some folks in a group I was in and it kind of blew my mind that I was talking to someone in Israel. It was like the world opened up. That is not novel today, but back then the idea of socializing and sharing ideas with people across the world in real-time (for free) was extremely exciting. Keep in mind back then long distance cost per minute, as did much of the dial-up internet.
About law enforcement: not much. Because I did see that minors were usually spared any real consequences, I mainly avoided anything that involved profit (though I once unwittingly bought a stolen modem for cheap, when it's that cheap you kind of know). There was an uptick of paranoia when Kevin Mitnick was busted (in the town I lived in), but for the most part we weren't doing the same kinds of crime he did (some of the folks I knew were, one ended up in prison for ~13 years). I also stopped being involved when I turned 18, which was a smart move. I got a visit from the FBI or state police (I don't remember) once, and my parents nearly shit a brick, and gave me a stern talking to because they were freaking out, but it turned out they were looking for a flasher who had been going around on Halloween! whew!
Thanks for sharing!
The reason was the juice. The excitement of sending stuff around the world before everyone else. I never cracked on x86 just a little bit with 6809.
I was a courier in late 90s(anyone recall FlashFXP). Fall of 1999 is when isonews.com(some old schoolers here will remember this website) got their homepage owned by the FBI. I left the scene that day.
IIRC the statute of limitations for the CFAA only has a statute of limitations of 2 years, but there are so many other laws outside the CFAA (and copyright, etc.) that you can violate.
