100% of the conversations on this website come from subreddits (main ones listed in another comment here). Overall I also monitor some forums, hacker news, and others for https://projectpiglet.com which identifies company insiders then recommends trades. So I don't feel comfortable with sharing exact sources.
Regarding the score - The paid version I'm offering to companies has said feature. It also has a bunch of other items as well, find duplicate accounts, automated related project notification, etc.
