someone posted a sad tale of having their AdSense account terminated. (The tale appears as
the 84th posting in the thread Responding to "I was terminated" threads.) A friend
of his tried to help him out by clicking on the ads (unbeknownst to him). Assuming this is
true, it's unfortunate, but it illustrates what a risky proposition AdSense is. As easily
as a friend might "help" you, an enemy or even a stranger might click on your ads enough to
get you booted from the program. IMO, it's a bad idea to rely on AdSense for revenue.
Maybe use it to cover the costs of a small website, but not much more.
