Are you ransoming this site to make money from Activision?
No. Personally, we don't care - and want no money. We took this domain for opportunistic giggles. If Activision were in a position to buy this domain, I'd ask them for a donation to a charity of my choice. Probably Help for Heroes - you know, those guys that don't get the ability to respawn when the timer hits zero...
Are you scared of being sued?
Not really. They could extradite me to the USA - I could do with a holiday.
