Lately we've all been getting these idiots who post to our blogs advertising products that they hope the gullible will click on.
Their attempts are very obvious. First they praise you for something you've written ("What an amazing insight into hemorrhoids!"). Then they try to segue their product into their observations ("And speaking of hemorrhoids, have you seen this article on Harry Reid?") The link is, of course, added there so that you can click on it and with every click, they make a little money.
One of you mentioned that spambots may have become more sophisticated.
They have. And they're called "gullible humans".
There's apparently a new "industry" which is taking advantage of the depression/recession (pick your term). People are paid miniscule amounts of cash for every spam bomb they can drop on helpless bloggers that result in click throughs.
Of course this will pay as well as the citizen journalism sites (pennies per article) and ultimately the fad will fade. But until then, be prepared for idiots.
