A web of trust feature is one that helps you make informed decisions about how to interact with people who are not in your direct social graph (i.e., people you follow) by using the social graph of those you do follow instead. Implicitly, you have some degree of trust in the people you follow, so you can use that web of trust as a proxy to figure out if you can trust them as well.

Features could include showing who of those you follow

- are following the person whose profile you’re viewing.

- muted a user

- reported a user

- reported a note or event
