A year ago the site was listed for sale and it looked like it sold for $300,000. The owner stated that it was an erroneous bid by a banned member of Flippa.
The owner tried to sell the site on Flippa over the past year. In one auction listing he mentioned that there was interest in just purchasing the domain.
Here is the link to the auction. You can click the little yellow triangle with the number seven inside to check out the other times it was listed.
