Closed early per this request from Stahlkocher, showing intent to resign.
Adminship removed by Spacebirdy per this request on Meta, made by ABF (to inform the stewards of Stahlkocher's wish, which Stahlkocher incorrectly placed on a local user page), which referencing this discussion. ++Lar: t/c 17:01, 1 March 2008 (UTC)
Stahlkocher was elected in 2004. On February 16, 2008 he deleted 1102 files. These deletions represent 75 % of Stahlkocher deletions since 2004.
In summer 2007 I requested permissions for some of Stahlkocher's uploads („Source:ADL“). ADL was an user on de.wikipedia.org. Since most of his photographs were taken during World War II and the following decades, I asked for an author. ADL claimed to be the heir of the photographers or to have received the files for purposes of his aviation club. He always denied to provide a written permission via Commons:OTRS. Some days ago, I found out that a ticket exists but it’s doesn't fulfil the requirements of Commons:Licensing (as two OTRS members told me). The subject came up some weeks ago, when another ADL image with missing permission and comprehensible licensing/source was marked with a “no source” template. The debate can be found here: User_talk:Polarlys/Archiv3#Image:Ar_95.OLUO.JPG (German). On February 15, 2008, Stahlkocher threatened to remove “all images created by third parties”, (intentionally?) misinterpreting one of my statements on works by other authors. He did so one day later:
deleting hundreds of files created by the United States Armed Forces (public domain, the only reason why we did not restore these images was a missing deeplink, but the reason for deletion (“no license”) was obviously wrong)
deleting files created by other users and/or transfered from de.wikpedia.org
deleting files in the public domain because of their age
The overwhelming part of this deletions is in no way connected with the causing debate. A lot of Stahlkochers reasons for deletions were obviously wrong and his improvable uploads (like the USAF files and files created by other users) demanded no immediate action resulting in such a degree of damage.
Remove My German is very poor (sadly), my licensing is not the best, however I can not explain this user's actions in any way other than a complete disregard for policy or a lack of knowledge of it. --Herbytalk thyme 19:45, 23 February 2008 (UTC)
Remove ack Marcus. -- Cecil 19:53, 23 February 2008 (UTC)
Remove Mass deletions because of en:WP:POINT alone is enough. In my book that's vandalism, and any admin who vandalises should not be an admin. The haphazardous or sometimes just very careless licensing just tops it off. (E.g. Image:Innenansicht Gasometer Oberhausen.jpg: claimed in 2006 to have author: "Nick Stahlkocher", source "Stahlkocher's collection", now deleted by him as "copyright violation".) Cleaning up this mess will take time, and apparently he's not interested in helping. At least he didn't answer when I asked him to. Lupo 20:32, 23 February 2008 (UTC)
Remove 1102 bad faith deletions = --sysop. Platonides 11:06, 28 February 2008 (UTC)
Comment. This requires very careful consideration. There are some very worrying aspects of this user's behaviour that seem to indicate a lack of understanding of Commons policies over a long period. To mass delete ones own files after they have been here for over a year (quite a bit more in some cases) with "no license" or "Out of scope" worries me a lot. I'll dig more later & others should do the same --Herbytalk thyme 14:18, 23 February 2008 (UTC)
