The internet has been an amazing innovation but it has created some new problems and one of these is spam.
We want our blog to be useful and read. We want people to be able to post comments. But lots of spam posts (links to scam websites or attempts to build links to get Google rankings) spoil this. The latest ploy seems to be to post general comments which aim to appeal to the writer’s vanity (ie thank-you for such a helpful article) and hide a link inside that. WordPress has some good spam filter capabilities but it is always playing catchup. It can be time-consuming to delete all these posts.
So we try to try to get a balance. This usually involves adding things which mean that you have to login and type in a word (captcha) but makes it harder to post spam (a task which is often done by software rather than a real person). We have also stopped posts on older articles.
So do we get the balance right? Any suggestions on how we can improve?
