I was testing something and tried to comment while not logged in, getting this:
Protected by: AVH First Defense Against Spam - WPMU DEV Version
how about showing some useful info to the blocked commenter, just in case it is actually a human? I mean, here I am commenting on my own site, being refused without knowing why.
Some pointer as to why I am being blocked would be nice.... might be my IP, might be Stop Forum Spam, might be Project Honeypot, etc..
