Whoops, there go my trousers
In the process of deleting 40-odd spam comments last night, I may have deleted an actual valid comment or two. At the last step in the process, when presented with a list of extracted domains to blacklist (or not) by MT-Blacklist, a couple of those domains were legitimate, leading me to think they might have been embedded in non-spam comments. At that point, however, the comments were already long gone. If yours was one of those comments, my apologies.
