Thank you for bringing this to our attention, however this is not us. We will have to look into how this ended up on the website.
Another strange thing, Flippa was showing that the site's Google Analytics is verified. But how? It reveals that Flippa's system isn't bulletproof and people may trick the system to show verified data about sites to scam people. I just want to beware you that never make any deal directly from Flippa, first contact being advertised site's administration through the real site and later make the deal on Flippa. It will save you from being scammed.
