Well, having migrated this blog over to its new Wordpress-based setup, I quickly discovered the downside to this arrangement: comment spam.
I never had any comment spam before. I don’t know whether the system I had before was just particularly resilient to spam (possibly because having the comments hosted externally from the blog itself was confusing to bots) or whether it was just unusual enough that nobody had bothered to write a bot for it. It may have been a combination of both. But whatever the reason, the only time I got comments I didn’t want, they were from real-life flesh-and-blood wankers rather than automated bots.
However, no sooner had I got my Wordpress installation set up than the comment spam began to trickle in. Just one every day or two to start with, but then suddenly a large stream of them started pouring in.
I managed to catch 95% of them by blacklisting the string “www.playlist.com/blog/entry/”. But this didn’t stop the comments being posted, just ensured that they were marked as spam and not displayed. I still had to go to the admin panel and delete all the spam every day or two. So I tried looking for a plug-in that would add a captcha or similar to the comments form. I know these aren’t usually completely reliable, but it would at least be worth a try.
In the end I installed a plug-in that supposedly stops bots from posting comments without needing a captcha, or indeed anything that is seen by users at all. It seems to be working so far; I haven’t received any more spam comments since installing it last night. I’ve also tried posting comments myself, both logged-in and anonymously and they still seem to work.
If one or two other people could post comments to confirm that everything is still working? Come to that, can those people who were checking this through the Atom or RSS feed also comment, so I can be sure they haven’t been stranded by the move? I think I set up the appropriate redirects, but it’s as well to be sure.
