Good luck with that. You'll get vanned quick doing that.
I suggest crawling the "deep net" if you are going to sell them. Also do your research on wherever you sell then because the Feds really do go undercover on those websites (like one time some guy got to an admin position, turns out he was FBI and took down info of everyone who was in the website, led to tons of arrest for fraud and identity theft)
I reported you to the feds. They have your IP address.
Don't steal money you asshole. Get a god damned job you lazy son of a bitch.
You're like 16
what the fuck do you need so many credit cards for.
Either your super greedy, or your goals are too high.
Why not just contact the site and tell them they need stuff fixed.
Chances are they will reward you for helping them = legit money.
Don't go to websites not saying they offer a bounty program most of the time they'll just blow you off thinking they have everything secured
