The suggested edit by an Anonymous User to this answer for the question Does Anushasan Parva, chapter 88 of the Mahabharata, allow cow sacrifice? got approved by Community.
This question on meta suggests Community bot could be human sometimes. Clearly that edit was meaningless.
So, on what criteria did Community accept that edit?
From Why does the Community ♦ user approve and reject edits?:
A reviewer either improves an edit, or rejects and replaces it with a different edit
When one is reviewing suggested edits, there are five available buttons, two of which allow the reviewer to edit the post themselves:
If the reviewer chooses Improve Edit and submits their improved form of it, the suggested edit is approved by Community ♦ (and immediately replaced by the improved one). If the reviewer chooses Reject and Edit, Community ♦ rejects the suggestion.
Also visit How do suggested edits work?:
One of the reviewers has chosen the option to "Improve" your suggested edit. In that case, depending on whether the reviewer has chosen to deem your suggested edit helpful, the Community user will approve or reject your edit.
And Why are my suggested edits here approved by Community♦? may be a straight to your question.
