The unix equivalent to the spam-filter was called the "kill file," or just "killfile." This kind of filter was implemented through a simple text file that the user could alter. Today, you can spot some of the old unix hacks by their use of the term "killfile" meaning to ignore someone.

Unfortunately, these sorts of filters are insufficient any more. They only allowed you to block on specific addresses, names, keywords, etc. But there are now newer systems that are adaptive. They can learn key phrases to ignore. A technique used by many spammers is to send identical emails from many different email addresses in the hopes that at least one will make it through the filter. The adaptive technique worked okay for a while. Unfortunately, the spammers are hard at work attempting to subvert filtering.

What you are seeing is not intended to make sense. In fact, it was specifically generated to NOT make sense - in order to get around the filtering. The real message might be embedded further in the post - or it could just be a link it is hoped you will click.

There should, of course, be penalties, starting with flensing, for spamming.

There are any number of excuses for not doing anything about it. Be assured it is the same manner of BS that made the do-not-call list so long in coming, the same sort of sleazy dishonesty that gives us a do-not-call list instead of a do-call list, the same sort of greedy, self-serving blather that allows phone companies to give out lines that don't show up correctly on *67.
