Chances are you’ve gotten a few comments that sort of read like they’re legitimate comments but something just seems off. The problem centers around the fact that there are computer generated comments that read well enough to get around our spam filters. In most cases the program randomly picks text from a large database of many options.
Yesterday, a friend of mine pointed to this comment submitted his WordPress site. In this case, the program messed up and didn’t send just one random message, it sent what looks like all of them. So, if you’re interested in glancing through a nearly 600-line example of all sorts of spam you may receive, you’ll get a better idea of what comment spam looks like.
