Hey,
By change I was confronted with a privacy issue. I have made a comment in the activity stream en placed it on twitter. From twitter you can link to the concerning comment. That's fine. However you also can see a toolbar (not signed in) with the option 'about' (see attachment). When a quest clicks on this link, he or she can see my whole profile. In the tab 'privacy' from my profile, all fields are set to 'registered only'.
In short: linking from a twitter message everyone can see my whole profile.
Can you tell me where the setting is to prevent this?
