I think we should simply have a higher tier, or secret cadre, of members with voting rights. I've said it before and I'll say it again. Presently you might have a tricky situation, a mod discussion, some disagreement how to proceed, the issue escalates, etc. The person that wants to act doesn't because other don't agree with the course of action. The committee stalls at inaction, as is often the case.
The moment you have a couple dozen voting members who can downvote content in secret, you can just reject content that's downvoted enough. You needn't know who voted so there's no recriminations or ganging up. Heck, they don't even need to be made public. No member needs know who has voting rights. You just post. Those that aren't posting right would get content removed and warnings that the Order doesn't think they're up to snuff. Downvoted posts can still be present and a change in voting thresholds could adjust to hit to sweet spot and return silenced posts that weren't all that bad.
It just needs noteworthy, trustable active members to be given the downvote option. That'd be everyone in the industry so they can downvote noise generators polluting technical discussions, and those who clearly want genuine good-faith discussions.
You wouldn't even need to ask their permission! Just give some people the power. If they don't want it, they don't have to use it.
You could come up with a fancy 3D inspired analogy about stochastic sampling and ground truth etc. for this, I'm sure.
Edit: Florin mentions above "Ignore Poster". Just needs another "Reject Post" and "Reject Poster" option for senior members, a simple button they can press they get on with talk or work. Instead of writing, "I'm fed up with this," you can vote (if you are a senior member) 1) with actual power to your opinion and 2) without contributing to the noise about the post/posters instead of the topic.
There are clearly a lot of invested 'lurkers' who'd probably make ideal senior executive members/secret-police/fairy godvoters who could be left to drop votes here and there and do a lot of work in a very distributed manner.
To start with, should this happen, if the system were even doable, you could just accumulate votes and then have a mod/admin look at what should go, what shouldn't and fine-tune before rolling out. Heck, mods could just be notified of content with too many downvotes to start with, to handle the final decision making.
