Yes, that is true, the current submissions uploaded to that category will be taken down shortly.

I guess we will see when that happens...

If you read the track rules you'll see that you need to record your runs in a priv server. Something like that shouldn't happen. There'll just be a bunch of tied runs.

that bug doesn't happen anymore and even if it did the timer would end at an absurd time

you'll get put on the same leaderboard
if it's in the game it's in the game and all players will have to deal with it
