He's going to take those trite "testimonials" as solid proof he's an amazing songwriter, rather than freelancers being nice to a paying customer. I'm sure they have their opinions about what a mess his songs are, but badmouthing a client, even one like Russ is bad for business. In a similar vein, most Instagram models take money from fans with the unspoken understanding that it's either a gift, or a payment for online fantasy. Since Russ doesn't understand things that are explained to him in plain English, he doesn't grasp that. For a model who makes at least part of her living from gifts/payments from fans, for her to block him on a payment app means he must have been even more demanding and creepy than he usually is. Normally, Insta models/OF girls put up with a lot to get their money, so he must have REALLY done something that pissed her off.
