Life beyond Adsense?

Out of the blue, I got the dreaded Adsense Account disabled message yesterday - I know of no reason why, nor are any of my sites linked to link farms or spammy places etc. Mostly they are hobbyist sites which may have an Amazon eshop attached, lots of decent articles and info and nothing connected to adult / porn/gaming sites. No-one in my household has clicked on the adverts either. My account is about 11 months old. Nor are there links suggesting people should click on ads. The email does not say it was invalid clicks though, it states Policy Violation.

Google as always are extremely vague and refuse to give a reason - I am cynical as the Adsense credit has just built up to where I could expect my first payout (it was only making small amounts anyway) and BANG...account disabled.

I don't really care about the power-addicted t***ers anyway, but just wonder what I can use as a direct replacement for the Adsense ads I had on the sites - Clickbank account I have and use, I guess affiliate sales places like CJ and Affiliate Window may be an option, but they all depend on affiliate sales - are there any direct PPC advertisers worth having where I can just paste code in and forget about the ad?

Any help and hints gratefully received - I guess I could register for another Adsense account using my company name details, but not sure I want to bother as Google is neither fair nor transparent and their actions seem arbitrary and ad hoc. Like they can be judge jury and executioner at any stage for anything, and as you have no idea what it is, you cannot defend yourself........and appeals are just a total waste of time as some nasty little creep hiding behind a keyboard just tosses out impersonal answers saying we hope you understand we banned you.......
