Who has control over a want ad character?
This is a bit of tricky business, so some quick terms. The Requester is the person who makes the original want ad. The Filler is the person who fills the want ad by making the character.
There are three levels of want ad:
Type A: Want ads with a lot of details which are heavily interconnected to another characters plot. These characters have a pre-existing relationship with the Requester's character, and have a myriad of details about them.
Type A characters must be approved by the Requester before they're posted for approval. These characters are under shared control (both requester and filler). If the requester (or filler) doesn't think things are working out, or feels the character has heavily deviated from the want ad, they can request the character be anonymized (see below). This can be done ideally by speaking to the other party, or via staff intervention. Type A characters cannot be unarchived or reapped without permission of the requester.
Type B: Want ads which involve a pre-existing connection to the Requester's character. Things like family members, clan members, people with the same origin, etc.
Type B characters must be approved by the Requester before they're posted for approval. These characters are under shared control (both requester and filler) for the first three months. If the requester (or filler) doesn't think things are working out, or feels the character has heavily deviated from the want ad, they can request the character be anonymized (see below). This can be done ideally by speaking to the other party, or via staff intervention. After three months of being consistently played, Type B players revert to Filler control. In that case, any shared details (family history, etc) needs to be shared, but the player is considered to have full control of their character. Type B characters can be unarchived without permission if they have been played for three months, but otherwise need Requester permission for reapping or restoring.
Type C: Want ads which involve in some way fulfilling a role. These commonly include relationship plotting, but can include other things that will happen in the future.
Type C characters do not need approval from the Requester before they can be posted. These characters are considered to be under the Filler's control from their creation. Type C characters can be unarchived or reapped freely, and there's not considered to be any obligation for the Filler to fulfill the want ad (although it is considered rude to not do so, especially without speaking to the Requester).
In the event that the Requester's related character is archived, any control the Requester had is considered lost.
Anonymization: Anonymization is the process of removing connections between two characters. The process is as follows:
1.) The Filler changes relevant information in the character (changes surnames, elements of backstory, etc.) to remove references to specific characters and plot elements associated with the Requester's character and plot.
2.) All interactions between the characters to that point are soft retconned as having happened between the Requester's character and a now off-screen version of the character they had put the Wanted Ad up for.
