I'm afraid that, recently, I've been getting quite overwhelmed with advertising masquerading as comments. Some have contained quite offensive material. After three and a half years (not a bad innings) I've had to turn on the word verification thing to intercept the automated "spam". That should reduce the moderation load a little.
I'm sorry if this is a nuisance for you, but please, please don't stop making the comments. They are one of the really rewarding features of this adventure.
