Spam prevention for published email addresses
I have a property with data type email and see it rendering as a normal mailto email link:
<a rel="nofollow" target="_blank" class="external text" href="mailto:firstname.lastname@example.org">email@example.com</a>.
Now, that's not the best for a public wiki, where we would risk spam to published mail addresses (and the fear of users of adding them in the form). It concerns not only 1 contact email but a lot of email addresses that this property gets assigned to.
Is there any way of altering this property to improve spam prevention (Wikipedia:Address munging)? Ideally, there would be a way to assign a CSS class to the property… where can I start?
