Named posting doesn’t need to expose one’s email address. You could just use the name. That was my point. There is no need to expose anyone’s email address to the world, be they technically knowledgeable people or otherwise.

I still believe your site is harmful to users unless the default is publishing with just the name and no email address, with an option of publishing with the email address if someone really wants to. The current defaults seem inverted.

I’ll stop with this comment since I’ve said enough.
