I have had a spam run in the last couple of days and was forced to delete a couple of hundred spam messages.
Despite the fact that I was reviewing every message if it was a valid comment or not (I unfortunately do not get many at the moment) it seems that I have overlooked about 90% of the real comments.
I have now placed a small unobtrusive barrier which might temporarily slow the amount of spam and I must look into the spam issue. It is driving me bonkers..
I sympathize with every other blogger who ever had to deal with this..
