Maybe. Tell me, Bill, do you use mailto links of the sort:
<a href="">Bill Christensen</a>

<a href=""></a>

If the latter, do you encode BOTH the mailto address and the linked text version? Or do you only encode the mailto part? Some people assume that spammer 'bots look for "mailto" while I assume they look for "@".

When I encode, I encode all forms of email addresses, including the linked-to text.

That is, I use:
<a href="mailto: encoded">encoded</a>

<a href="mailto: encoded">NOT-encoded</a>

and, as I said, only the un-encoded version has received spam. Perhaps it's not a matter of YMMV, but of technique...
