Are you saying that people spend a lot of money to buy multiple Steam accounts (that have CS:GO on them), so that they can slowly rotate which account they use for playing, so that they avoid gaining ranks and being matched with players that are as good as them, so that they can keep dominating lesser skilled players every time they play?
Yes, that's exactly what people do. Although the spending money part is kind of optional now, since the game is free to play. And it's not really "a lot", it's like 1 AAA game, for most likely way more hours of entertainment.
This is also something that happens in pretty much every multiplayer game with skill based matchmaking that exists. However, other games are much better at mitigating this. In LoL for example, your MMR doesn't decay at all. It does get soft-reset once a year when the new season starts, but that reset is quite soft and you can't "stack" multiple years of resets on top of each other. If you had top 1% MMR in 2015, you still have top 1-2% MMR. All games could do more to prevent this, simply by changing how their matchmaking works, but CSGO really takes the cake in terms of requiring an absolute minimum amount of effort, plus actually "forcing" people to smurf unintentionally, just because they took a long break from the game. It's comical at this point.
Wow, how unbelievably insecure do you have to be to do that? In CS1.6, I was always appreciative of the chance to play against higher skilled players, becuase that's how you get better and better.
