Google Blog on Google Money Scams
It’s some good tips, although as usual the people who most need to read it will probably never see it. But they do go over the legitimate ways you can earn money from Google (AdSense and the Google Affiliate Network), plus some of the symptoms of these and other scams people try using Google’s name.
I particularly liked this section:
Some sales pitches use the word “Google” or other trademarks right in their name with targeted phrases like “cash,” “pay day,” “money,” “secrets,” “home business,” etc. If you can’t find it on our list of Google products or on the business solutions page, don’t trust it.
A great point for anyone facing any product making big claims while using some other company’s name.
