There are a few "automatically protect questions" requests out there, but I'd like to add another twist.
I'd like to request that questions that have three or more deleted answers by users with <50 rep be automatically protected.
The reasoning behind this is that we have lots and lots of "not an answer" flags in the mod queue. But we cannot protect a question from the mod queue, so we have to open each answer, evaluate if the question needs protecting, then protect it.
This process takes a long time, and can definitely be automated, as the only thing you really need to check is how many new users are posting non-answers or are spamming their awful products.
