Moderate Uploads to Combat Spam

[milezzz]

I have a board recently come under attack from trolls and just general spammers and it got so bad I had to turn off account creation. I looked over the code and I don't see any scaffolding for a moderation queue for uploads. I guess ideally it would work something like this:

1. If toggled in config.yaml require Moderators+ to review all uploads of perhaps just "regular" user ranks before they're visible on the front end
2. These images could show up in the /posts display perhaps with a colored outline to highlight that they need approval. Mass approving post controls would be handy here too
3. In the post edit view have a toggle for: Approved | Hidden

I think this should be added by default as most boards getting any decent traffic will be susceptible to this annoying spam. Has anyone attempted this?

Doubling this request, since I've also had to deal with spam a couple of times.

I'd like this too, also an option to have moderation queue selectable for each user class/rank. Eg anonymous users are subjected to moderation but power users are not.
