I get what you are saying, however all ambiguity is lost when the player
is warned on multiple occasions about that they are doing. Which in
this case was the scenario. Trying to argue around the facts even when
the player in question mentions that they were warned and then repeated
the exact same behaviour is pointless.

As for what it says well its no greater a punishment than being denied.

As with all rules, enforcement is subject to the judgement of the
Immortal staff, and failure to comply with the above may result in
punishment, including denial of the offending character.
