It's no longer in business - seems to be 404 lately.... but some fucktard decided they didn't like one of my sites and posted it in there and since all the other lemmings just follow orders, i've had 3 years of nothing but hassles from it. But I kept the domain running and double checked my traffic sources and well.. i'm still here - making more honest money than ever...
I wasn't about to cave in over some newbies understanding of traffic, but hey, it's a big ocean out there and sounds like a misunderstanding. Just be professional about it and let the people make their decisions - the buyers you want are the ones who can look at this type of situation and make an informed decision based on the facts - the ones who don't - you wouldn't want to do business with anyways.
