What is the "Edited by" in some of questions?

Question

I have see " Edited by (a profile name) " in the next line of the some questions. What is it?

Answer 1

It means that it has been edited by a moderator; usually to add the mfd tag to the question, or to replace innapropriate content with <redacted>.

Answer 2

Apart from what Rowsej mentioned, we also edit bad tags, and (rarely, ) misspelled terms in the thread, code links in thread titles, etc. If you find that your thread/post has been edited, feel free to ping the mod in question for an explanation (if one isn't obvious).

Answer 3

I have also seen a case where the grammar in the question was improved by a moderator to make the question clearer.
