Access to a particular mjolnir (whether that mjolnir is still run) is managed by the owner.
If we remove an owner's access to a mjolnir, we also end up closing out anyone else in that mjolnir's management room from using the mjolnir.
What I mean is that we can have the following:
1.User A is in good standing.
User A creates a Mjölnir.
User A steps down, letting user B be the de facto owner of this Mjölnir.
User A becomes an obnoxious troll and gets kicked out from the server.
We remove A's authorization to generate Mjölniren (I think I'm going to keep that plural :) ).
Any Mjölnir of A gets closed.
B loses a Mjölnir.
The only reason I can think of for indexing Mjölniren by creator is to do 6, no?
