On my main wordpress blog I run Akismet to detect SPAM comments. This is the first line of defence
Lately this regime has been letting a few through each day.
This is unusual, but shows that spammers are now willing to pay real humans to sit down and leave comments on blogs.
It killed spam comments dead for the last few days. So far so good.
My web site visitors (not here, the self hosted one that I haven’t linked to) tend to be not be computer enthusiasts, so don’t have their own blog to legitimately link to, so I don’t think they will care.
