CSGO Massive Bot Lobby Problem - Why Does Valve Not Care?

Early morning on the west coast, virtually ALL CSGO Vertigo games are being played by 6-player bot lobbies.

I believe they rotate which player "wins" on the team of 4 real players, while having the remaining 5 afk in spawn until the game ends.

The only way to get into lobbies such as this is when the botter fucks up and accidentally accepts the final 10th invite without every one of his bots queued up.

Realistically, you will queue up for Vertigo 100s of times. Each/every single time the botter will cancel the matchmaking process and hope that the real person doesn't queue up again.

I have submitted several tickets (and obviously reported users unfortunate enough to get me in their lobby), but Valve seems to imply they can't do anything about this...
