I've been getting increasing amounts of spam in the comments on the Blog - Blogger does seem to be catching some of it but some is creeping through. It is usually just very bland "your site is great etc - please click on my (dodgy) Link" but I got some pornograpic spam yesterday, which was published on the site - don't worry all been deleted now.
Because of this I have now changed the comments settings, so that all comments have to be moderated, its a bit of a pain, but the alternative is to put a captcha on, and I like most people hate them with avengence !
What do you do about spam on your Blog ? What works well for other people ? (Moderated !) comments below !
