Use a pseudonym on the net? Leave comments on blogs or newsgroups? Well, you could be in trouble with the law.
Under new legislation recently signed by Dubya, it is now an offence to “cause annoyance” on the internet without disclosing your true identity. So if you flame someone on a site, perhaps in their comments, and do so using a pseudonym, then you could be liable for fines or up to two years in the clink. Sledgehammer and walnut, anyone?
