Interesting, isn't it? I was surprised - I always thought that, eg, evil teenage girls writing lies in letters to hurt each other was shitty, but I didn't really expect 'I saw your boyfriend with another girl ha ha ha' (if a lie) to be _illegal_ Also, does it make it illegal to write things down in private correspondance that it's legal to say? That would be Odd. Presumably there is lots of case law making it make more sense?
