Why are my track&cups deleted?

For example, when I post a track of "Baby Park", there's a bug that somehow deletes it after a few hours, did I do something wrong?

also happened to me
i kept tryin to post a track called Japan Tokyo 1 and it keeps getting deleted so i had to modify it

square/oval layout QM tracks aren't allowed

Stolen Map from internet or Stolen from another Creator on MKPC.

User @MKWiiBestGame made GCN Baby Park and added pipes in the middle that kinda looks like Baby Mario.

How dose that look like Baby Mario?💀💀💀to me it just looks like a whole bunch of pipes spammed💀

Doesn't change shit it's still just overdone layout, that isn't allowed

he tried I guess

the game thinks it’s better than a square/oval because of the pipes

A few months ago Wargor added a program that automatically deletes default square tracks since there was an occasion where they kept being spammed. Idk if it also works with ovals or not, but if you add decors it's probably safe from auto deleting.

As for complete mode tracks, I delete anything that's stolen or just not even a real track.

i've also made a baby park map, but now that i've heard about the "no-oval and square tracks rule", i will add some things like bowser's ship.
