What does that web of trust entail?

Last one I saw was Nostrgram but it was more of a view score for indicating how many shared followers you have

It shouldn't imply that all posts signed by a public key are the same kind of content. Accounts should be able to self categorize as sensitive or warning for the content. If other services want to do analysis and clients partner with those services thats all well and good but that cant be the expected approach for nostr as a whole. Clients wanting to moderate experiences should probably not be rendering global by default
