I run a competition/contest website which lists competitions. Users view the details of the listing and then link off to the external competition page.
I have noticed a similar website that has a page after the user enters the competition that they go to which says something like “please wait while we validate your answer to the competition. Please take a moment to visit our sponsors” which has some Adsense on. The page then redirects to a thank you page.
Is this allowed?
