This question already has an answer here:
We all know StackOverflow is community driven, so edits are allowed. However users with low rep's edits must be approved in the suggested edits review area.
It is said that "Community" approves edits when a reviewer goes to edit your edit and then closes the edit dialogue without changing anything. - Why are my suggested edits here approved by Community♦?
But how does "Community" reject an edit?
