Restrict or ban smurfs

It's insane how many people you run into that have:

XvT 70% Win rate

XvP 70% Win rate

XvZ 0% Win rate

Here's my suggestions on how this could be fixed:

- Restrict accounts that quit in the first 30 seconds too many times in a row (this is like what chess.com does with aborting too often)

- Make it so they have to win 3 games vs their lowest win rate race to get out.

When you play someone who has a 70% chance of winning, you can tell before you even check their match history. It is not fun. Losing to someone equally skilled let's you learn, you can cover gaps in your knowledge. But smurfs don't win because of anything you did or didn't do, there is nothing to learn.
