If an instance is added to The Bad Space in error, that admin can reach out to have it removed. This happens. Admins do this every day.
The FSEP proposal makes a number of points:
* There needs to be more info about how/why an instance was added
* There needs to be more than one person making add / remove decisions
* The Bad Space won't be the only provider
* Human mods make mistakes
* The false negative/positive rate is as important as the weaponized abuse rate
None of this is controversial.
