The same user has been able to do three different suggested edit approvals on the same answer in the space of 5 minutes. Not only that, two of the suggested edits came from the same user (different to the approver). Here is a screenshot*:
As you can see from the image this is not the only user who is doing this. This might be by design, but if so I think it is a bad design.
Why can one user make two small suggested edits to the same answer in the space of a couple of minutes?
Why can one user review edits on the same question three times in the space of five minutes?
This sort of thing is annoying me a lot. To me this smells like people taking the piss, gaming the system, having a laugh at the expense of good reviewers who try to do a decent job. It shows me there are people out there who cannot be trusted with reviews - is it time to raise the reputation threshold for reviewing suggested edits? Or is it time to develop a new anti-gaming script to identify this sort of thing?
*sorry about the lack of freehand circles. Issues with dodgy review queue actions have left me capable of only doing stright lines at the moment.
