That was uncalled for.
When I've let other domains expire that I've held for several years, even if they had little traffic, they've gotten snapped up by domain mirror companies. When we were looking at setting this site up there were a lot of different websites already taken. I'd rather it go to someone legitimately interested in doing something with it. I'm not under any delusion that it's worth thousands of bucks. I'd take $50, mostly for the trouble of transferring the domain.
You don't have to be an asshole about it.
