As already explained, no they didn't!

In the future, if you want to find out why any edits are rejected, there is a section in your profile under *Activity* → *all actions* → *suggestions*.

In this case:

> suggested [rejected edit](https://askubuntu.com/review/suggested-edits/816830) on New to installing Ubuntu

Click on *rejected edit*, not the title:

> Rejected 12 hours ago:  
Community♦ reviewed this 12 hours ago: **Reject**  
This edit conflicted with a subsequent edit.

It was auto-rejected by the system user *Community♦*, because a different edit was submitted at the same time by another user. Bad luck!
