As I struggle / writhe in agony under a torrent of comment spam on my Tips Archive and this Blog I hunt around for ways to allow real people to leave comments if they wish, while keeping out the “holdem” excretions (more than 225 at current count). Somehow now I’ve blocked all human commenting at the Tips Archive, but that doesn’t stop this creep. Sigh.
Anyway, if you also have a WordPress blog then you should refer to WordPress : Tackling Comment Spam
Comment spam is a fact of life if you have a blog, but using WordPress, you have not only some good built-in tools at your disposal, but also some excellent plugins and methods you can use which are constantly being developed. Please do not think that you can ignore the issue of comment spam – you cannot. This page represents all the methods I am currently aware of.
