preventing email harvesting

will this work

[expat123]

Hello all,
I run community site and would like to prevent users' email addresses from being harvested.

I am considering storing email addresses in a mysql database (where they reside anyway) and have them retrieved once a user clicks a submit button. Would this work or can spiders simulate a post and thus retrieve the email address?

thanks.

If you send the message after the submit button is pressed, there's no actual page with the email address in it, so it can't be harvested.
