Deleted circuits

Sometimes I just upload a new track but it gets deleted and there aren't any stupid reasons such as bad word usage or racism.
To this day only 2 of my circuits literally vanished:
-"Literally every Zooya track": a track that just spells "Zooya"
-"That one track where you complete laps at the speed of light": it was just a glitch showcase track where laps can be 0.06 seconds long.
What was wrong with these?

First, half of your tracks have the same name.
Second, you shouldn't have 'ultimate shortcuts' so the second one was pointless.
