AdSense offers a number of ad formats and advertising products. Publishers are encouraged to experiment with a variety of placements, provided the following policies are respected:
No Google ad may be placed on any non-content-based pages.
I'd not show ads, update my site asap and then display Adsense again after the update.
But if your page has a lack of outbound links, that likely IS a problem. As has been noted here about a million times, any gimmicks designed to force or to strongly encourage users to click the ads will get you severely smart priced, if not banned.
As always, asking Google is the only way of getting a definitive answer.
