yesterday the following edit was made https://math.stackexchange.com/posts/33730/revisions which deletes content from an (very old) answer. Taking liberty to edit and perform such censorship/deletion seems not appropriate as it is not community wiki. He should have rolled back rather than deleted bit the he doesn't like.

And now someone else did it https://math.stackexchange.com/posts/33730/revisions

Thank you for keeping an eye out for things like this. For what it is worth, in the future, it suffices to flag the post in question for moderator attention; it is not necessary to open up a discussion on Meta.

  • $\begingroup$ The answer was locked, and a notice was added. "Community" unlocked it and removed the notice. Is this the work of a person, or automatic/software? $\endgroup$ Jan 28, 2013 at 2:03

    $\begingroup$ The imposed lock was a timed-lock, which can be set for a fixed period. After the period expires, the community user automatically unlocks the post. $\endgroup$ Jan 28, 2013 at 8:46
