    This question was asked many years ago, but I have not seen and
    answer.  Is there a collection of &quot;Known Web Bug Servers&quot; out
    there?  In addition to <a href="http://msgtag.com" target="_blank">msgtag.com</a>, I have found <a href="http://advmailservice.com" target="_blank">advmailservice.com</a>
    to also be a Web Bug service (front end is <a href="http://pointofmail.com" target="_blank">pointofmail.com</a>).  Are
    there any more out there?<br>
