Basically I was looking around the queue and found this suggested edit: https://stats.stackexchange.com/review/suggested-edits/117203
It became obvious to me the user was having difficulties with the account(s), so he posted an update with another account as an edit.
The suggested edit was approved (not by me, I skipped it). But I can see reasons to actually reject it. The user should be asked to merge the accounts first. We should treat the edit as if it was another user.
Why? Because it becomes too simple to vandalize posts doing this. I've never seen it, but it became obvious to me after seeing people posting updates with multiple accounts how easy it would be to pretend you're another person and suggest an update, and how it would easily pass in the queue.
I've seen it reported in meta before, so I'm posting this thread as discussion: should these edits be accepted before accounts are merged?
I want to know it so I can act accordingly in the review queue.
