its only actual grab spamming if you keep rushing up for the same grab over and over regardless of the situation. If you are just punishing, though, that's different. I have to explain to SO many people that I'm not spamming Mila's tackle, heck i'm not even USING it, but that EVERYTHING leads to her mounting you lol. Giggity.
