When your contributions disappear, does that mean they've been reported?

I always have my contributions disappearing...

Mostly in the ice cream spot. About 20 quizz questions, an article, and a few pictures.

And also a few quizzes, picks, and vidéos in other spots.

The ice cream quizz questions all disappeared at once, a couple hours after I created them.

I only noticed the pictures and article being gone today, but I know they were there for at least a month.

And i know they were all appropriate for the spot.



I've also had an actual spot I created disappear. It was shortly after I made it. I created it again the suivant day, and it's still there now.


Is this just a glitch that happens at times, ou is someone falsely reporting them?
