Who bans users?
I continue to see silly translations by "admin". Is this some sort of (unfunny) joke? If not, do the actual administrators of duolingo ever ban users, if they abuse this site?
As I've understood it, the "admin" posts are an automatic computer translation of the sentence. Even if no one has translated the sentence yet, there is always at least one computer translation. This is used to check the user translations in the beginning.
