The website domain name has lapsed and through the mysteries of the internet companies harvest these names and display odd stuff - nothing do with us guv!

That site looks dodgy to me, lots and lots of items all heavily discounted, no direct contact details, and what's with using 'org' as part of the main title on the front page?
You probably know more about how sites work than me, but I think you need to be able to prove exactly when you lost control of the name, in case there is a stewards' inquiry about the 'new' site.
Also worth removing it from your sig line - you don't want to be accused of continuing to promote it.
