I've been trying several spam filter plugins, and this looked good...but it ended it it was blocking all my users. No good.
I installed it and tried commenting and received this error:
Go back and try again.
Error: empty answer. 
i thought it was great, since spam died off the second i installed it. unfortunately, so did all other comments, and i soon learned from readers that none of them were able to leave comments. they all received an error that the date field needed to be blank, and to try again. since the date field was apparently filling itself in, it viewed everyone as a spammer.
