But if reputation is based on several factors, account age, comments/posts made, votes received, and anonymous peer t0 peer reputation voting (perhaps weighted by reputation of the voter), then accounts would only gain reputation (and therefore be able receive rewards and voting power) if they are real people. 1 person with 100 accounts would have to work 24 hours per day to gain even a small reputation - but i think it would become obvious that they are not real so reputation would not be gained. Here is a draft i made in 30 minutes today (doesnt include the peer to peer voting yet). It's just food for thought
