I have passed 3500 reputation on a beta site, so I have both access to the 10K tools and the ability to protect things.
However, the protection ability is somewhat tough to use, because there isn't an easy way to find those questions which need protecting.
In my experience, the questions which are in need of protection are those which have many deleted answers, as stated in the privilege page.
There are other potential problems associated with questions generating many deleted answers:
- A bunch of link-only deleted answers? Maybe the question is asking for a favorite outside reference, and needs to be closed.
- Very low quality deleted answers? It's possible the question itself needs some editing/deletion
We have a list of posts generating lots of comments - and we can't do too much beyond flagging for comments. Why not have a list of lots-of-deleted-answers questions, which 10k'ers can actually do something about?
