I have a special Q2A installation in which I tried to re-create a magazine column on psychological advice. I decide that all the askers (or may be the answerers too) will be anonymous by modifying post_meta_who function. In a nutshell, they are registered members, but when they post questions, the author information is assigned with intelligence agent code like #007. Well, you can guess it's the userid.
Now I need to block the viewing of such pages like /users, and also user/elizabeth, user/elizabeth/questions...
I don't want any stalkers here. So, how do I do that and the Q&A page will still survive future updates?
