Meta: if a post is dead due to flagging / banning, but you find it valuable, you can "vouch" for it. With several (perhaps one?) users vouching, the post is back from dead.

Click on the "30 minutes ago" link next to a dead post's author name to view this individual post, and now a "vouch" link should be available. Click it to perform vouching, done.

This function not available for some users, depending on karma threshold and perhaps other factors.

I've never vouched for a post and had it not come back so I think when the account is shadow-banned at least it only takes one vote. I also very rarely vouch for it's possible there are additional factors at play.
