This is a proof of concept addon to remove banned members from the View Members page unless requested with the group filter.
This demonstrates overloading a standard model in order to modify the member query.
NOTE: this will not work on versions earlier than 2.4.0
Install the extension as per the EE docs. There is no configuration.
This has been tested on a relatively stock install of EE 2.4.0 without a significant number of other addons. Please exercise caution when testing this and make sure to backup your data.
