(I've been approached  at Meta by a swwiki bureaucrat who asked me if I could pass his request there , so here I am).
The sw.wikipedia folks kindly requests you to please disable anonymous users from creating content over there. I think removing 'createpage' and 'createtalk' permissions from the '*' group would do it.
The also asked me if they could disable anonymous editting entirely, which I told that I thought it'd not be possible in principle.
They have voted for this change. The poll is linked in the URL field of this bug.
Thanks in advance.
