OK, I give up on this one. Following recent heartache about a deluge of smelly spam to this blog, I recall that I have noticed one feature of a couple of the early spam posts: somewhere in the post, there would be a Greek omega character (ω) in place of a 'w' in one or more of the words. Once I had noticed it, I started to look for it, and pretty much every one had an omega somewhere in it.
Now, I don't have enough brains to be able to rack them properly, but I did get out the magnifying glass and a pair of tweezers and fiddle with them a bit. And I can't for the life of me work out why this should be. Is it an attempt to create words that will be readable but unrecognised by spam filters? Or are all the spammers, English-illiterate though some of them are, all closet Greek scholars, channelling Thucidides?
