Didn't know about the mailto: part of the harvester, but we've been using
&#064; instead of @ in mailto links on web pages for years with the same
lack of spam.  Probably will go back and see if it doesn't break if I use
the entity for ':' now, based on your report.

Can't say it will help, but it can't hurt.  In fact, I hope that the simple
method keeps working on other people's pages well enough that harvesters
don't get more sophisticated...

I put our spamtrap address on every page in a comment, because I want it to
be harvested all over.  Don't know how often it gets harvested but, even
once is useful.
