Configurable whitelisting or unwhitelisting of groups of people.
Groups and its members are set in the config, which has example values to help get you started. Also adds command /masswhitelist (also usable as "masswl" or "wl) where you can reload the config or (un)whitelist groups as you please.

Command guide:
/masswhitelist whitelist (groupname): Whitelists the group with that name in the config.
/masswhitelist remove (groupname): Removes the group with that name in the config from the whitelist.
/masswhitelist reload: Reloads the config file to updates groups/names.

Command requires permission "masswhitelist.whitelist" to be ran.
