As a fat Indian top, I’ve noticed the same thing, especially amongst the younger “no load refused” cumdumps.
You agree on the time, the general area, and WhatsApp/kik and then just as you’re about to walk out the door boom they’ve vanished. But you know they’ll still online and they’re still showing read receipts.
I honestly find bi or straight curious guys are better for anon fuck and go. They usually only care about the cock and not the person, or if they care about the person they’re also into humiliation so it turns them on to actually take any cock. They also tend to ask a lot less questions about sti status.
