I know well the Community bot for putting random unanswered questions to the front page from time to time. A few time ago, I discovered an uncommon role of the bot putting it as the author of a suggested edit (because the actual suggestion came from an anonymous user).
Now I'm wondering under which circumstances the Community bot may be enforcing a "Marked as duplicate" closure?
I flagged this post as a duplicate, which added the usual automated "possible duplicate" comment. I expected this post to go through the usual voting process, unless a human moderator enforces the post closure. However just a few minutes later I saw the post closure has indeed be enforced (no votes, only me and Community mentioned), but by the Community bot and without apparently involving anyone else (does the bot trusts me so much? ;) ).
I also searched this on meta.se, it seems there used to be an answer for this question, but there seems to be some buggy thing going around and the search result links to an unrelated question :( :
