There are haverstors on discord and Reddit that track posts revealing evidence of having actual sums of money. Your account is put on list(s) which are sold to exploiters / hackers / manipulators.
It's pretty easy to ignore PMs/DMs and more sophisticated social engineering, but the worst is when low level mod staff who have deeper account access (like IP addresses) sell your data like Meta staff were doing.
These employees usually earn very little money and are in 3rd world countries, and are fired anyway so it's an easy side gig while they have it. Just be careful.
