This is really bad.I also remain in constant fear of my adsense account getting banned.I don't make blogging as my full time job just for this uncertainty.
They don't ban people without a reason. One of my websites received complain once and the site was blocked from displaying ads. After proving the complain wrong, my ads were put back on in less than 24 hours!
There are many alternatives to Google AdSense. If you can earn good money with PPC you should be also able to earn with affiliate programs. Simply promote some products which can be useful for your visitors.
hmmn... good suggestion, but quiet often Google doesn't contact or reply to queries. Once, it disables the Adsense account it treats people unfairly. My sympathies are with those who have lost their Adsense accounts. Best of luck…
