This is usually handled by reducing the editing grace period (defaults to 5 minutes / 300 seconds) and post edit time limit (defaults to 60 days / 86400 minutes) in the site settings. I see absolutely no reason for a bunch of other custom features when those site settings control it perfectly.
Also note that thanks to @gerhard people who flagged a post to threshold are now notified when the flagged post was edited.
Not sure what you mean Jeff - how is it handled when they have 60 days to come back and edit their older posts and nobody is notified of such edits?
Our edit period is 12 hours and they sneak in even with that. But edit spam was just one aspect - being able to see who’s regularly doing housekeeping tasks around the forum would be incredibly handy.
Even that is too low and too much of an inconvenience for genuine users - they shouldn’t have to suffer. As I mentioned though, edit spam is just one aspect. Having these kind of logs makes it super easy for Admins to get an overview of which members are ‘helping out’ i.e potential mod material.
I hadn’t seen the data explorer plugin, however I still think this is one of those features that once you have, you would find difficult to live without (if you have a busy or relatively busy forum) particularly if it is expanded to have a similar (configurable) page for moderators.
