Why not just get another email address that can be used for stuff you don't want going to your personal email addy?
Try this one, Mail.com. I use that email provider for craigslist. The site inundated with scammers asking you to go a verification address or a pay site where you have to pay to view. And yes, CC details required. Hahaha, no chance!
Or set up a yahoo email addy? Then if you think your punting email addy is being hacked, delete it.
