This is a proposition for an edit filter that, if implemented, would prevent new (not semiconfirmed) users from creating subpages of other user's userspace and usertalk space, and from directly editing another user's subpages (talk permitted). This does not prohibit them from creating another user's userpage, or main talk page. This could be compared to semi-protection on subpages in namespaces User and User Talk, with exceptions and not applying to the user's own subpages.

Rationale
I have 'never seen the ability to create subpages on other users used constructively, instead I've only seen it used by vandal users to try and put vandalism under the radar (as users are not directly informed a subpage of their userpage got created), and very occasionally seen new users create the userpage of someone who doesn't have an account, usually for spam. Alternative variations:

1. Exclude the "prevent editing" portion of the whole proposal.

2. Narrow down the scope, only apply to subpage names which contain vandalism terms (which itself solves much of the problem)
