Well quite frankly, just from my point of view, i'm thinking:

Who would buy such a name like www.adultnetsuprize.com ? It doesn't mean anything and just seems to look like Adultnetsurprise to me... so i'd think the person who bought that name wanted to get traffic from Adultnetsurprise

It's just not a commom domain name and to register it, you'd have to have back thoughts in your mind

Just my 2 cents

It's like i would have : scorpiocreations and someone gets scorpiocreationz... i'd be pissed too.
