It's no joke. Last Thursday, President Bush signed into law a prohibition on posting annoying Web messages or sending annoying e-mail messages without disclosing your true identity. In other words, it's OK to flame someone on a mailing list or in a blog as long as you do it under your real name. Thank Congress for small favors, I guess. This ridiculous prohibition, which would likely imperil much of Usenet, is buried in the so-called Violence Against Women and Department of Justice Reauthorization Act. Criminal penalties include stiff fines and two years in prison.
