Now go outside and look at the sky.
It seems that my MT-Blacklist actually deleted all comments from the site... I noticed that I suddenly got ZERO comment spam - there was an entry in the blacklist that not only stopped all comments from being posted, but during a regular cleaning also threw out all old comments.
Well. That sucked.
Apologies to everybody whose comments were sent to the big bitblender in the sky.
Comments are now open again.
