Two acts ago I was plat 3 when the season ended. I didn't play at all last act. This act comes along, I win 4/5 placements, mvp in all 4 of the wins, and then place silver 1. Is there something I'm missing that happened behind the scenes?

I was in bronze, now gold, and I feel like the higher I go the worse kinda people I meet. The last 5 comp games I've had someone either being blatantly racist/homophobic, hot micing, flaming the other team or just being unnecessarily edgy....
