I wouldn't worry. AdSense typically performs poorly on forums and leaderboards tend to perform better than banners (which is what I assume you used before). Your current CTR is not what I'd consider high, though there's no universal high/low CTR. Considering my experience with fraud detection systems and the likelihood Google's is much more advanced than anything I've touched I wouldn't be concerned. I doubt it would happen, but even if the increased CTR flagged your site for review unless there's actually something fraudulent taking place I wouldn't expect that they'd contact you.

I'm with richmondsteve. Even a sudden jump in impressions doesn't panic Google :-) . There have been sites that got mentioned on big news sites and suddenly saw their traffic jump 100 fold but without running into any Adsense problems.
I wouldn't worry. You aren't supposed to disclose CTR figures but those figures are well within what some content sites get on a regular basis. Whether it's on par for your industry and your type of content/layout etc I wouldn't be able to tell you.

Dropping the ads on a forum = much higher ctr. But it also means less impressions.

If it would ease your mind, I think installing one of the third-party tracking scripts being developed here would help you find out if there is anybody clicking non-stop on the ads.
BTW, I also think that the fact that the ads are no longer in the forums, that you changed size and colors could be behind it.

I think that's whats behind it too, but that much of an increase in CTR is waaaay more than I thought possible or even reasonable. Thanks anyway, it's good to hear that it's not as far out of the realms of possibility as I thought.

Google will be happy. Less work for their servers (less impressions).
