We don’t currently send notifications to editors when edits are made - this was stopped because the geographic subscription notifications process was too computationally expense to run on the configuration we had at the time, we may be able to enable that again in the future. That’s an open item for someone to tackle.
Regarding malicious edits, our only process currently is to fix them. Malicious edits haven’t really been a thing before because they are normally quite obvious, the more likely cause is someone accidentally moved the marker while editing and didn’t fix it. A reviewer can check if the edits makes some sense but they can’t usually know if the details are indeed correct.
