Can ch's delete your entries?

I am asking because I am missing a couple of names in the social chat contest. I submitted 4 names but only one rated and the other 3 are gone.

Refresh the page.I had that happen in a contest today, and I refreshed the page and they came back up.Probably just a glitch.

Oops! I withdrew my comments bc started thread for wrong contest. My apologies I was reading my activity feed wrong.
