Whilst viewing someone else's profile, click on "view more" underneath Votes, you'll get a Page Not Found error.
NOTE: It works when you do it on your own profile
Try it on my StackOverflow profile HERE. When logged in as someone else and viewing my profile,
Scroll to the bottom for the 'votes' section. This section incorrectly shows a 'view more' link which should be private:
Clicking this link will bring you to
/users/1039608/mattytommo?tab=votes, which is not viewable if you're not the listed user (as it should be).
The 'view more' link should not be shown.
