I would tend to think the rating system will handle a lot of this for us. I would hate to see anything additional (algorithms, bots etc) used to achieve this end. People can police people and we already have these tools to use. Wouldn't it be possible for a new user to get flagged somehow if they borrowed a picture of a place (not a person) and while you or I might fight to maintain our reputation a new user may just as likely go back to.... any of the other choices. I would like to see an option where people could fully verify their account through the site..... be it steemit or third party. Something that removes all question as to wether the person is who they say they are. Even that as a voluntary thing.
