how could i possibly be risking jail time?
Depending on jurisdiction, you can be facing criminal charges for violating personal secrecy laws by stealing, storing, transferring, and exposing information.
Plus, as many gambling organizations understand value of list such as this, they may attempt to purchase list from you through blind intermediary. Then you are identified (at minimum, circumstantially) and goose is cooked. Gambling houses often link to "organized" crime or at least shady characters.
Smartest move is cover tracks and delete all trace of these data. Second smartest, or more stupid, is cover tracks, encrypt data, hide data away from home, and forget about for year or two. Then you can make money from data.
More stupid is not forget and research, network, and such in gambling data area in years before using data.
If must use data, decrease probability of you as thief by increase pool of people who could possibly have these data.
But smartest move is make money without these data. Delete these post and ask people quoting you to delete post in thread. Criminal talk is bad for everyone.
