I was perplexed by this post. It sounded as if the complaint dealt with rabbit sex, i.e., hopping a bunny. But why should that be an issue on our servers, I wondered, other than the occasional member like Hxtr who will screw a pigeon if he can catch it? So I looked it up, and it apparently is a refernce to persons constantly jumping during game play, so as to escape the customary chest-level line of fire.
Well, I don't think GIs went through Europe hopping every step - very hard on the knees. But I don't doubt that they hopped on occasion, perhaps when stepping on a mine or something. But in any event, I checked the XI Rules of Play, a massive tome ensconced in the vault at XI Corporate. And though it makes no mention of the aforementioned bunnyhopping, there is nowhere to be found any rule against such a modus operandi.
And so, in short, you're fucked.
Go forth, and bunnyhop as you will.
