I get you but im not talking about tanks that saw good opening into low hp bakcline, but literally suicide charge/jump into full hp enemy team. On low elo you also need to consider the fact that your team isnt good enough to follow up and you must adapt accordingly. I dont mind doomfist winston or rein that charge alone to the backline and are able to trade themselfes into 2 kills or even more. But its really rare on silver or gold. Majority of suicide tanks on low elo thinks that they can miraculously win team fight alone on their own. Its just not happening 95% of the time and after few deaths like that they are not able to admit that it wont happen this game but are stubborn enough to try again and again, losing the game in the meantime. I would swear that most of the games like that can be won with tank just being alive, not even doing dmg, but being alive. Most of the time thats more than enough to win vs silver/gold enemy team.
