I am aware that I lose reputation for suggested edits if the final approver of the edit is removed. But now there is an extraneous "reverted" event to go along with user removal:
Source: my reputation history on Academia.
The edit was not reverted, it's still there. In any case, I should not lose 2 points twice for the total of -4. And indeed, my reputation only dropped from 131 to 129 despite what the history suggests.
So the line with "-2 reverted" is a bug.
A more extreme example: Ben Miller on Sports got 21 "reverted" events on 2017-06-30, none of which should be there. His rep loss is 42, not 84 as the reputation history says.
