    The probability of anyone in Russia, Ukraine, Belarus, or
    Kazakhstan, becoming an SR member, asymptotically approaches zero. 
    The probability of spams, scams, spyware, malware, etc. coming from
    those locations, is high.  The ratio of spam to real correspondence
    from yandex.com addresses is presently 1.0 : 0. <br>
    <br>
    That's a lousy risk/benefit ratio.  So IMHO ban the hell out of
    yandex.com and any other domain that shows itself to be a
    significant source of spam etc. <br>
    <br>
    "Open" as in "accepting" does not equal "open" as in "unprotected." 
    We are not under any obligation to have no collective immune
    system.  Species without immune defenses don't even last long enough
    to become footnotes in archaeology.  <br>
