To echo a little of what the others have said or implied: Maybe you are a D4 player? That's no disrespect intended. It's higher by double than I or most players could ever get. The point is simply that (whether or not the game has cheaters, whether or not you stack) every single player in this game has a ceiling. I think people forget that, or worse, they remember one of the gimme seasons where Respawn handed out master badges like free samples at BJ's. And now they expect that level of reward in every season, and are not interested in hearing that "insert rank here" is their natural high-water mark for their skill level, stack status, internet connection, or quality of cheats. It just is what it is. I've never understood all the hurt feelings and hand wringing over ranks - obviously, given my inability to achieve one of any value - but I sympathize that it matters to you. But still, your life would be better if it mattered a little less???
In the end, as already noted, just start a secondary and lay waste to silver, gold, and platinum again. And if you do that and the season still isn't over, just start another one. Respawn doesn't care if you screw over other players which explains why virtually everyone does it. So don't be proud or principled. No one else is.
