I have seen many edit suggestions approved which I consider to be minor edits to old posts (which bump them to the front page), or to actually reduce the quality or readability of the post. Other problems also occur, but these appear to be the most common. As such, I would like to submit for discussion the feature request in the title:
When reviewing suggested edits, cancel rejection and approval votes. More precisely, a suggested edit would only be approved after the difference between the number of approval votes and the number of rejection votes reaches the threshold.
If this feature request is approved, it may be appropriate to also implement the following:
Remove suggested edits which have accumulated a certain number of rejection votes (for example, three rejection votes).
