From the Protected Questions FAQ we have the following:
Do unprotect questions that aren’t currently attracting a lot of attention and don’t have a long history of unproductive answers.
Now, I recently became aware of a way of listing all Protected posts, by using the 10k+ tools (for <10k users seems that a
isprotected search operator is a feature still being considered, but not available at the moment). This tool can be found at: https://workplace.stackexchange.com/tools/protected-questions
That tool shows that we currently have 710 Protected questions, the oldest one dating back to 2012!
This got me wondering, should we be unprotecting questions that qualify for such in a more active manner? (I already handled 2 of them, but wanted to hear what everyone thinks before pouring myself into the other 708 posts).
