[wiki]: More restrictive edit policies?

[Timothy D. Ginn]

In the past few days I've been encountering the same problem with a (non-FIRST-related) wiki that I run.

There I've got it set so that users must be logged in to make changes. For months that was enough, but, I'm now considering some form of Capcha as in the past few days there's been an annoying number of spam posts (I consider 9 since the beginning, all of which have been in the past few days, an annoying number).
