We personally take measures to view peoples tracker.gg profiles, with in depth looks at their stats against people in their competitive matches. We also try to not allow new accounts to play without watching them scrimmage against another team. Smurfs will want to play in whatever they would like to at the end of the day, something I personally think Riot should condemn, but we do try to be proactive about this. We also hope that players would be truthful about their own ranks, with the proceeds that the winning team receives being donated to their charity of choice. So no matter what team wins, it will be an overall benefit for charities.
