Concerns about the PvP and why it might not succeed, though I want it to very much!

The best decision would have been to give each player their own privacy settings. That way, people who can't handle competition can hide behind their anonymity.

I think you got it other way around. Trolling, trash talks, harrassments, are done by the players that play badly. Players that can handle competition, will not trash talks because they are the winning one. The one that are making harrasmetns are usually the losers after the ballsita match
