I have a pretty good spam filter (Akismet) for this blog, but now and then a spam message still gets through trying to sell Viagra or vacations to Bahamas or whatever. Strangely enough a lot of them are commenting on a blog post that never generated any valid comments.
So eventually it occurred to my thick skull that I have the ability to turn comments off. Rather than pick and choose, I have changed my settings to automatically disallow comments after 60 days.
Apologies to all who really really want to talk about something I posted last year.
That comment time-out plugin/feature is a good one. It has virtually eliminated all spam “escapes” from Askimet in the last couple of years.
