I tried to access member profile pages and it asked me to log in. The image you posted is for search results...
Oh, sorry for being confusing: I logged out and accessed it by hovering over the user name. It provided a summary of that user's activity (location, posts, likes). See screenshot. The number of posts is clickable and clicking on it took me to the screen called 'search results' I posted before.
I just did a quick test and it does it for other members too. It was set differently on the previous forum version so I thought I'd mention it in case it is important.

You can adjust some things in your privacy settings of your profile under the point: "privacy" what can be seen by guests and members for example. Though maybe you still can be searched.
Thanks Gawan, I do have everything set to 'members'. There is an option in privacy settings called "allow users to view your details on your profile page" and that's set to members. I guess it only refers to the profile page only.
