So, I looked at it for a couple min. There might be something with the conversations tab, but not sure. The only thing that I could come up with is send them a message to look at your profile and add a way to contact you privately there like your facebook or something. You momentarily change your settings to private and only share with people you follow. That way you do not display it to everyone. Probably a better way but that might be the easiest. ... anyone else .. like I said maybe something with the conversations tab as well where you can do more.
