Dear Friend,
The issue I am writing to you about is of the utmost importance and seriousness: it involves a grave threat to our freedom of expression and communication. In brief, it concerns a sinister imposition of US-based, but world-wide, political censorship in the guise of "filtering of spam".
As we all know, the problem of spam (unwanted email, some of it distasteful or noxious) has reached enormous proportions and has become not only a nuisance, but -- by clogging the email system -- a real danger to free email communications.
Faced with this situation, various remedies are being tried.
