Only Follower (besides Broadcaster & Bot) should be able to receive Moderator access
Am requesting this feature, because at the moment you can't deny receiving Moderator access without resorting to extreme measures.
There's already a setting that allows non-followers not to get sub-gifted, but it would be nice if there was either a default or a toggle that allowed non-followers not to get granted moderator access too.
Additionally, it helps a little with chat security (granting the wrong username access etc).
Ergo, it makes viewers keep their privacy (being able to automatically dodge moderator grants) and it makes the mechanic of broadcasters granting them more secure.
Have added "Broadcaster & Bot" in the title as exceptions, since they can't follow the channel by default.
As for un-following when being Moderator: perhaps it would trigger a textual warning noting that it would cause the viewer to lose their elevated access levels (depending on whether the Broadcaster's or Viewer's settings are setup that way).
