There is a way to address that kind of style of attack in kayfabe though. I've said in my RPs before that half of the battle would be the mind games, the verbal sparring, etc. Ideally if I would get into a situation where my opponent wasn't posting I would say that I was in their head, and that's why they're too scared to post a promo, and if it's that way with uploading a promo then beating them in the ring would be no sweat.

Still, people don't like that in general and that's fair.
