SPAM factoid...

BBC's Click OnLine did an informal test of how e-mail addresses get
listed for receiving spam. They found that the most effective way was
when the address occurred in a web page. They concluded that the address
harvesters seemed to crawl the web looking for addresses. Just sending
e-mail was not the way the address was harvested. They had a neat trick
to encode e-mail addresses in a bit of obscure JavaScript that would
simple be ignored by harvesters. My e-mail address in a web page is:
<script type="text/javascript">
<!--

"y%=127;o+=String.fromCharCode(x.charCodeAt(i)^(y++));}return o;}f(\"wf{tmrr" +

I have yet to see how I can get all places with my address like this. But e-mail
harvesters do not see an address here. Pop it in an HTML block and see my address.
There is a web site that will generate these for you. If interested, I can look
it up. Note that as I can only control local instances of this, I still get far
too many spam per day...
Maybe the SxS could encode e-mail addresses?
