Signature links for non-customers appear to guests

Not sure if this is intentional, but if you are a guest, and view posts/threads and someone who is not a vBSEO owner (black username) has a signature link, their links are visible

If you are a guest and viewing the same thread any vBSEO customers (orange username) their signature links are not visible.

I'm sure this was just a slight over look, or maybe it should be the other way around?

Example: Logout and view AdSense Revenue Share Hack the second to last poster has a black username, but signature viewable by guests

He cheated & added those links directly within the post text.
