Strange Writing indeed

A friend sent me the following spam email:

To my 'selected' strange-minded friends:

Now, you may ask yourself why a university would be looking at such seemingly trivial pursuits. The reason has to do with intellectual property and the need to maintain control. For example, suppose you had written a paper containing some important company secrets. The specific section containing the secrets has been redacted but the abstract of your article is open to discovery by Google or other web crawling web-bots. Now let's say you "encrypt" the abstract so that humans can continue to understand it but computers cannot. This is similar to the test blogger uses to screen out non-human comments.
