In SCA combat to wrap-shot someone has little fear; you can almost bind your opponent's shield/weapon simply by proximity, and the primary thing you leave yourself open to as a counter is them throwing a wrap at you, and little else. Historically, it would probably turn to ringen/wrestling/throw (as most fechtbuchs show); in SCA context, you can't be thrown, you can't grab weapons/arms... it's an inherent "safety net" to close in and wrap.
The primary "problem" with wrap shots is that while it makes a great sound with rattan for a "kill", it seems a less efficient idea with a real sword. The generation of force on a wrap shot is considerably less than a "well planted, well struck" blow like a forward-stepping zornhau. More (proper) power, bigger wound, faster kill(s). The up side is many people seem to have worn less armor on their back/rear, so getting a good strike with less or no armor is less important since there could be less "resistance" to getting at flesh. However, you'd have to be *quick* at getting in to strike and kill - quick enough that your opponent doesn't grapple you or bind your weapon.
SCA has some similarity to late-period tournaments where they used wooden clubs instead of swords, and somewhat similar to the "counted blows" competitions. It has it's ties to being historically based, and I've found it to be, in general, pretty good about not claiming it's 100% historical. I'd have no problem with SCA publications being used as a supporting source for the sake of discussion, as long as it wasn't in an attempt to prove that "historically they did this, because the SCA does, and the SCA is a historical society, so....".
I'm surprised (or maybe not) to hear that a moderator was the one who said that. You have to be careful in other people's sandboxes, sometimes they get snippy and seem to have no "people skills". I had a post deleted and a warning issued by a moderator on another forum because I posted that Medieval Fight Book (history channel show) was available on YouTube for people who didn't or couldn't see it. I didn't even post a link to it. First time I ever had any communication with the moderators.

What really pissed me off even more was that other people posted about Youtube after my post was pulled, and nothing happened to their posts. I was "special". I rarely go there any more, but I rarely posted there and there wasn't much interesting anyway save for a few random threads ... so no loss for me.
Sounds like you might want to just ignore that forum, if that's an option?
