I doubt most people are going to finely tune their relay list like this. easier to just do WoT and put people outside your trust network into the bottom of threads with media blurred.

It could be. I think WoT with some manual WoT bump-up is a great option for an Inbox relay. WoT is terrible for Outbox, though (a simple paid relay is easier). The key part is making it setup of the multiple relay lists we already use easier. If I sign up for Nostr.wine, for instance, there should be a tool that puts each of the relays they serve in the right list for me.
How do you onboard new users into WoT? New users won't be in WoT initially which still means their on-boarding experience is tarnished by spam. Paid relays help, but then that is still expecting new users to finely tune relay lists and pay for relay services to start with.
Sometimes freedom of content like this just requires the user to go through some hoops to see only the content they wish to see.
If each user has their own WoT inbox relay, and the WoT is just local of that server, then there could be a simple approval screens for new pubkeys that reply to the user. The user could approve each of those at night in some simple left/right screen for ok, not ok. Then something to mass reject all the spams. Maybe some little tool to evaluate the video and image content and already separate into a list for easy rejection.
If the WoT is shared, I think an active moderation could be very cool. Similar to what I said before, but for all accounts at the same time. Which I think is already happening in some form in existing WoT relays.
WoT doesn’t mean ban them outright, at least in our implementation. It just means put them in a low priority section of the app
