Three harassing comments from a person who was a homophobe and a misogynist. He predictably accused me of censoring him, but I would censor anyone who used a four-letter word in a comment, even a comment I liked. He also slandered a well-known feminist critic by name. A no-brainer.
Unlike the (many) other trolls I've had over the past 8 months, this one left a paper trail -- I have his hotmail account and his (pseudonymous) blogger/blogspot URL. Does blogger accept complaints?
