Summary
So, in order to counter advertising messages, users should not use a username, and groups should not use a public group
As a user, if you do not want your favorite username to be used by others, you can create a channel and occupy this username.
As a group owner, you can use the group username you originally wanted to create a channel, and then prompt users in the channel to use the private group's invite link.
