I’ve been spending a lot of time deleting comment and pingback spam from my two blogs (most of it from the moderation queue). My first impulse was to ban comments and pingbacks completely — after all, some blogs seem to do fine without them, and most people technically-oriented enough to read Quoderat already have their own blogs that they can use to comment on mine.
After some thought, however, I’ve decided on a compromise — I’m going to leave postings from the current and previous month open for comments, but close any older ones. That should eliminate a lot of the spam, but still allow discussion on recent postings. I might tighten that up a bit more, but I’ll give it a chance, first.
How is everyone else dealing with comment/pingback/traceback spam? My blog isn’t all that popular — it must be much worse for blogs with high rankings.
