Adsense on multiple sites

What if one site is not to Google's liking?

I'm always thinking of new sites to put up, and now with Adsense around the profit motive is there. If you have a couple of major sites with adsense and then add the adsense to some smaller sites, is it conceivable that one day google may suspend the whole thing just because of putting them on the smaller sites? Not that the smaller sites would go against the TOS, but it won't be the same quality as the bigger site(s).

No.

I asked them for permission about including their code into new web sites but they answered that there is no need to ask - that they monitor and check automtically if everything complies to their terms of service.

I have web sites covering totally different topics, so this particular feature of AdSense is of very big importance to me.
