Describe the bug/issue

As far as I know, this is a big exploit, although I did not test it. I am assuming it should be reported as a bug, even though behavior is as intended.
When an opponent forfeits a game, the player gets a win. And disconnection due to internet issues is counted as forfeit.
This makes for a possibly extremely easy levels farm.
A player only needs an aide to get into games with and the aide forfeits every game which makes the player level up rapidly.

I discovered this as today I was playing in a practice room with my friend, but she was having internet issues. So every time I tried to start a game, she'd disconnect during the game and I'd gain points (which I didn't notice until level up). If I recall correctly, I leveled up within 3 games. And for the last game we tried, she had disconnected even before landing a single piece. And yet I gained points. Well we gave up at that point, but I noticed this can be exploited.

Reproducing

1. Create a multiplayer room
2. Set it to practice mode (or to 2 player limit)
3. Make an aide join the room
4. Start a game
5. Aide forfeits
6. Repeat
7. You get insanely rapid effortless level ups

Expected behavior

Expected behavior is basically that a player gains points and ranks up by skill matches. There is no in-game glitch, just unintentional emergence of rules, so I'm not sure what to write here.

Screenshots

I have no screenshots, and I can't find any relevant game logs. The room we were playing in was #XQDS

Console logs

No logs

Additional context

I do have a suggestion, maybe win by forfeit points can be based on how long the game had lasted. Since its compensation points, it can be compensation for the player's time. This will also reduce the exploit as it will no longer be as effortless as hopping into and leaving game so rapidly.

We do consider this an alt policy violation, even with anonymous accounts, and have reasonable automated scanning for such behavior. That is to say: it's against the rules. We deal with high profile exploiters when they come up, and the community usually behaves itself. No point in writing a fundamental change to what's essentially a glorified playtime number right now. (That may change in the future if #359 decides to leverage XP.)
