Really one of 2 things need to happen to make the CKing of other people through an application.
1: When party A wants to CK party B and party A puts a CK application in to be reviewed. Party B should be reached out to, and ensure that everything party A is claiming to be true. Unfortunately with that option party B might never come IG again out of fear of getting their character CKd or they may act more cautious to avoid being killed.
2: Have administration provide more attention to CK appeals. Have administration have a faster turnaround time on CK appeals and not wait months to even get a response from an admin that the situation is being looked into.
