Askimet caught two spam comments yesterday:
"car insurance | http://carinsurancecar.blogspot.com
IP: 85.192.165.116
car insurance…"
The weird thing is that our blog (http://blogs.gmfus.org/) requires users to create an account and log in before commenting and there is no user by the name of 'car insurance'.
At first I thought he created an account, left spam and deleted his account, but there is no skip in user ID numbers, so I don't think that's possible.
Any idea how they got through to leave a comment?
