I've noticed whenever it says "Expanded Search" you're bound to get matched up with higher level players. It is really frustrating when you play a few close matches against people well-matched to you, only to get matched up with a random gold or plat guy when you're ranked bronze.
Also, anyone immediately placing at rank 100, it's because you have no points earned yet and most everyone in your division has points. Win one match and you'll probably jump up a few places.
I especially loved the part of the Quake TNT when Jeff had to go into the Matrix-like server code and start kicking players. That kind of computer know-how is no longer an essential part of gaming, as it was for people who played stuff other than Tetris and Minesweeper.
