This is apparently a new and very gross scam apparently coined as a “cash slave”.
The one that many Tumblr users are falling for isn’t as obvious as the other one I found while fact checking. They’re usually very similar to porn bots and you probably didn’t notice how pornographic pay/pi/gbi’s header and icon are. I do not know just how much this scammer is doing or if they’re doing anything other than stealing personal information but if you know a minor who’s trying to get free money through this
WARN THEM THAT ITS STEALING BANKING INFORMATION AND PROBABLY DOING MUCH WORSE!
