can I stop someone from posting on my wall?

I think blocking an user only stops them from PMing you, not posting on your wall. However, Du can change your settings so that only people you're a Fan of, oder only yourself, can write on your wall.

Go to your Profil and select Bearbeiten Profile. Scroll to the bottom of the page. You'll find a drop down box. It's set to "anyone" Von default but Du can change it to stop people from posting on your wall. Click Abschicken to save your changes.

Yes and no. Blocking someone prevents them from commenting directly on your Wand but they can still do it if Du post on any of the club walls. As I sagte on my last post--there's no surefire way to block people on this site. It's probably one of the least safe/secure sites I've ever been on in that way.

I'm not sure. I think Du should just block the user and it will be enough.
