A real grab bag there The auditing panels purpose should be to provide transparency and accountability to Oversight and Checkuser  The manner in which that purpose is achieved is likely to involve responding to complaints from the community responding to issues raised by other Checkusers and Oversighter and maybe some selfinitiated actions  Responding means asking questions of the various parties and making some kind of public statement about the finding The Checkuser log has a reason field it should always be filled out with an informative comment  However requiring checkusers to maintain separate records is a very bad idea  Data retained by Checkusers is theoretically subject to subpoena just like the Checkuser logs from the Foundation  If someone wants to force the Foundation to disclose someones IP for libel in a BLP for example a clever and wikiwise lawyer would also subpoena the Foundation to reveal the names and addresses of any Checkuser who ran a related check and then subpoena the Checkuser to turn over any data that was retained personally  Since Checkuser data expires after a given time personal records kept by Checkusers could be a goldmine of information for the right litigant  It should be up to the individual Checkuser to decide whether they want to take that risk and which cases if any and what information if any to retain  Mandating it would make them all potentially subject to the hassle of responding to subpoenas  If a Checkuser fails to leave an informative log summary and when contacted by the panel is unable to satisfactorily explain a check that can be taken into account by the panel Like any jury the panel can decide for itself whether a claim of I dont remember is credible or evasion The primary goal is transparency and responsibility  I dont see any reason not to take old cases  Sometimes there will be enough information in the log to answer especially regarding Oversight since the diff itself is now visible via the log and if there is not a polite We looked into your complaint but determined that too much time had elapsed to do a proper investigation will have to do  Certainly whatever page is set up to describe the process should include advice to make complaints as timely as possible
