Danny Sullivan stripped perfectly legit code from Search Engine Land because he was accused to be a spammer, although the CSS code in question is in no way deceitful.
StandardZilla slams poor Tamar just reporting a WebProWorld thread, but does an excellent job in explaining why image replacement is not search engine spam but a sound thing to do. Google's recently updated guidelines need to tell more clearly that optimizing for particular user agents is not considered deceitful cloaking per se. This would prevent Danny from stripping (code) not for Matt or Google but for lurid assclowns producing canards.
