I was actually considering bidding on that in TDNAM, but decided against it. I think the ed suffix hurts it a little, but I would say low-mid $xx in the current market.
Nice catch CO. I don't think the JohnDoe.scammed.us thing will work... for one, UD already has something similar and I'm sure she'll be upset if you have something like that. Also, as you can see screwed.us' traffic died down after being dugg (while on digg's frontpage, less than 100 new complaints were filed) so maybe the idea isn't as good as it was conceived to be.
