[Plugin: Another WordPress Classifieds Plugin] How to stop spam contacts? I am using the math valida

Hi all,

First to the author. Thank you for making this plugin available, it works great for our neighborhood association website for neighbors to support each other’s local businesses:)

Just last night, I was copied on a couple of emails that went to people who had listed ads using the plugin. It looks like it came from the contact form for their individual ads.

Is there anything I can do to stop this?
