I don't know how old OP is but I did a lot of dumb stuff on the internet 25+ years ago when I was a teenager. Including writing viruses and stealing credit card information. I'm glad things were a lot different back then.
That goes well beyond doing “dumb stuff on the Internet”
Wonder what the implications of just taking the CC numbers 20 years ago would have been?
It doesn't translate to today's Internet.
(This would have been ~25 years ago, maybe a bit more)
