I think you're right. I IM'd him a week ago and still no reply.
Perhaps, most tellingly, his OF states:
"Please don’t ask to meet in person 🫶🏻 It could result in our accounts being permanently suspended"
So his RM could mean he's looking only for a $uper $ugar Daddy or he's willing to play for $ if you're someone he'd otherwise meet on Grinder, collaborate with on OF, etc., etc., etc.
