It's intentional wiping that sucks, not the accidental stuff. I'm talking watching a player hump a bunker to wipe paint off, or doing exaggerated slides to shift it, even sliding into discarded paint to obscure hits. I can happily say I've never done it intentionaly, this is due to my fail-safe method of being lit up in every game I play, the Diablo car-wash would have to work for me to wipe on the field.
