Thanks Cmorrell, that was very helpful advice! It's a google blog, which was set up by someone else originally. We have now adjusted some settings, so that comments are no longer public. The cowards might be put off if they can't read their own rubbish on-line anymore. Or they might get even more vicious and angry...We'll have a look at the IP settings.
Some anonymous followers have just joined recently through google friendsconnect using weird code (see below) - could they be virused or is that just googlefriendsconnect thing?
