5 clicks, 0 revenue

Adsense new to page

[Powdork]

I recently received a note from a webmaster notifying me content at the end of one of my links was no longer valid. I changed the links to reflect the new content and decided that I should have adsense in the section devoted to the website (an historic estate). Today was the first day for the revised section and I had 5 clicks for 0 revenue. I'm guessing they came from the webmaster of the estate site since I sent him an email notifying him I had updated the content.
Any other ideas?

PSA's as adsense has not spidered the content?

Are they pay per action ads? Below the ad it will say: Refferal Ads by Google

Not ppaction (don't I have to be signed up for that?).

This site is tightly themed, and the new ads that appeared immediately after uploading were the same that show across the site. Also, this would be a huge ctr for psa's, especially since there is only one block=one psa usually. It feels like one person clicking multiple times. However, today's ctr for the entire site is double its monthly average.
