The tactics employed by comment spammers continue to fascinate me, but I have noticed a new trend, which indicates either a new trend or adaption from the spammers – which reminds me of the way bacteria respond to antibiotics – or perhaps just indicates I am being over-sensitive.
Twice in the last 48 hours I have had comments from people who are clearly responding to the content of the blog post but who are also linking to an explicitly and solely commercial page: one was an XML editor and the other was a video on “how to be a hacker” (of the LulzSec variety as opposed to kernel patcher type).
Now, this blog is currently doing pretty well in Google on a number of the technical areas it discusses and traffic is slowly rising as a result. (Interestingly Google ranks the HTTPS pages much higher than their HTTP cousins, but that’s another issue and not one I am going to discuss here, because I really have no idea why that is.)
Therefore it may well be quite valuable to comment spam this site if you are looking for people interested in XSLT or the Kronecker delta or whatever. But you are also up against a pretty good spam filter in terms of Akismet, so the usual “your blog is great” crap is not going to make it.
So, like a bacterium faced with penicillin the spammers mutate and devote more energy to survival. Or, it is just that people who sell a product are genuinely interested in what I write here – though something tells me that it is more likely to be the first!
