Hi Yonna, Thanks for the link, a very interesting read indeed.
I am guessing that there must have been a small instance where IMPS didn't renew their domain name quick enough and it was bought up by an email directory company looking to make a fast profit as the domain was a busy one. I know they definitely owned the name before this date and I don't remember smurfs.com ever directing to another website so there must have been a little slip up along the way but only for a little while.
Having been caught up in the troubles in the past (before this by the looks of it) I can only ever advise people not to use smurf etc. because it is really not worth the hassle in the long run.
