XF 1.5 Change "contact us" to be viewable by banned users

I'm getting incredibly frustrated by how XF won't allow the "contact us" box to be used by people who've been banned. It seems I can enable it only by giving banned users the "view" permission... which also gives them the ability to reply to PMs in their inbox (ugh).

How can I change this? Is it a source code edit?

Thanks for any help.
