There are currently 2 types of +/-: Support/Refute - this allows you to assess the credibility of a post, and you must provide a citation. This affects the credibility score of the post. Trust/Doubt - this allows you to "predict" the credibility of a post, and if it turns out you predicted correctly, your credibility increases. And vice versa. The +/- actions are designed to have some friction. You are either required to find a supporting/refuting citation, or you are putting your cred on the line. The "contributed to the conversation" isn't something I am directly addressing, but am hopeful that good actors will stay on topic, and that credibility scores will sort out the good actors from the bad. Yes, actions are weighted by the cred of the voter. The selling of accounts is an interesting one. Haven't thought about that. Of course, once misinformation is posted, their cred will go down. One thought is to monitor the cred trend of accounts, and abrupt changes could be looked into. Thanks for your great feedback.
