Thanks for the opinions all, I'm leaning with the opinion that once the surfer hits the freesite then yes, it's that freesites surfer, and quite right of course.
I'll still be allowing those warningpages.com as exits
Also, funny it mentioned about exit links being checked more than sponsor links, I'm the same myself, as Raw Alex said, to make sure it is actually non-adult, and as UW says, I only really click a sponsor link if something seems 'fishy'.
Thanks again for the advice all, much appreciated
