Brehs Ja Rule isn't a real scammer....he's just a DESPERATE businessman trying to get rich quick. Like how desperate people believe these pyramid scheme dudes preying on them
In the Hulu doc, Rick Ross was fukking with Billy with that credit card. Billy gave him a bag of cash and Rick Ross was like

let's get it. Ja met Billy during the credit card business too.
But once that business failed, Rick Ross peeped Billy was in over his head and cut ties

while Ja Rule stayed and was like "what's next Billy?"
If Ja wasn't desperate for cash, he wouldn't have even entertained the festival but we know Ja still trying to get back on his feet after all the money troubles from the past.
