What you are asking for is, in fact, an exception which cannot be granted. Our rules apply equally to everyone on the forum and that is non-negotiable.
I encourage you to review the rules for the Personal Threads category once again. Specifically:
Roleplay threads of any kind do not qualify as ‘personal threads’.
You have already been provided with a solution on how to archive your threads yourself and you are more than welcome to use it, but please understand that this is our final decision on this topic. We cannot cater to individual one-use cases, since we have the greater good of the forums as a whole to bear in mind.
Have a great day,
Mari
