The security reason seems very unlikely to be the origin, but it does partly explain its continued popularity, as well as its continual mutation. Given that a large portion of what is on the internet is capable of being indexed, filed, and pushed into a database to make it easier to search, if you don't want to be found, it becomes even more valuable to have some 4r90+ that's difficult to decipher.

It's the same reason some people use N@zi, or joe@nospamaol.com (in a newsgroup posting) -- it's a way to keep out of purely machine-based searches.
