I do feel the need to clarify, since the user in Scenario 2 called me out on it. The hypothetical user is presently "indefinitely blocked" on on enwiki not banned.
The line between "indefinitely blocked" and "community banned" is a very narrow one. I suspect the person is banned. The only way I can see an indefinite block not being a ban is if it's just pending something (the conclusion of a discussion, the person in question agreeing to certain conditions, or whatever). A community ban is an indefinite block that no admin is willing to undo - if an admin were willing to undo this block, they would have done so.
