This morning some Chinese spambot called "Alex" managed in 4 minutes to leave 16 comments on random posts saying "this is cool" or "this is actually really cool" and then a lot of Chinese script. Google translator told me that most of this script was 'porn' or 'movies'. So instead of changing my settings to only allowing those with other sign-ins to comment (which would exclude most of the people who actually comment on this blog!) I've enabled comment moderation.
I thought it was in particular bad taste that "Alex" chose the post about finding out that the kitten Anise was dead to leave the comment "this is actually really cool!" Poor form indeed spambot, poor form.
