From my experience, the reviews filtered out are often reviews by folks with small or no networks. I saw my wife's reviews filtered out when she first had an account, before she added friends or connected the account to facebook (not sure which one did it, this was years and years ago). I'm not saying this is a good system, just my observation of one factor.

Yea I'm sure brand new users have lesser ranking on Yelp Sort. My experience is just from talking to the Yelp Account Managers and seeing our bad reviews be Page 1 one month, and pushed to a further page the next month.
