When a nation CTEs, its name is released and a new nation is founded with the same name, it appears that all posts on RMBs made by the old ("Ancient") nation are attributed to the new nation -- and the new nation has control (editing, self-deleting) over them. Is this an intended feature or a bug?
Some examples can be seen in the posts here. The nations Firebird1470, Inosensia, DRACOEN, Piscenn, Roslynne and Delta of the labyrinth are all nations which CTEd and have been refounded with the released name (at least some of them for nostalgic/fun reasons). All the posts on the linked page obviously belong to the original incarnations, but are still attributed to the current incarnations. The owner of the current incarnation of Delta of the Labyrinth was today even able to self-delete the posts made by its previous incarnation on that page.
(In case you need confirmation that the posts really have been deleted today like I said, I have an archive of the RMB from last month (made using my tool) which can prove it)
