yesterday the following edit was made 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

agreed. I will roll back. – robjohn Jan 26 '13 at 12:52

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.

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? – The Chaz 2.0 Jan 28 '13 at 2:03
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. – Willie Wong Jan 28 '13 at 8:46
