Access to certain channels only with verification by email etc.

I think it would be better if individual channels (not the entire server) were only accessible to verified users. So you could operate channels that only have access to those who have previously verified, e.g. with a valid e-mail address, etc. All other users would be excluded from this one channel.

Unfortunately, as far as I know, verification is only possible for the entire server. This should be changed so that access to individual channels can also be made dependent on verification without requiring verification from all users.
