Because the game can be fixed easily. I mean I did like an hour after it was uploaded. The staff are the ones who upload the games and have the final say so they would need to ban themselves then
Jokes aside, I do believe that rudimentary play testing should happen before a game is uploaded to the game page to at least make sure it is playable the whole way through. I mean shit just give me a link to it and I'll fix the damn games before they are uploaded. They don't even have to give me a position or fancy title, I don't want any of that, I would gladly troubleshoot uploads before they are released. I already have been fixing most of the broken MTLs posted here anyways.
