Basically I just want to ask whether a room owner can see deleted room, transcript, messages in that room.
This came up in a recent conversation in chat with another user who mentioned that they cannot see the room I linked to. I have tested and I saw that when I'm not logged in, I do not see the room either. So I thought that this is privilege tied somehow with the reputation. (Still, they were able to see a room which was frozen rather than deleted.)
I searched a bit and found this answer which says that a deleted room should be visible to "moderators, room owners, and users with at least 10k network reputation". But when I look at the room info, the user in question is listed there as the only room owner.
So now I am not really sure whether the information provided in the linked answer is exactly correct. (Still I have decided to tag this support rather than bug, since it is quite probable that there are some other rules about this I am unaware of.)
