This user account is a botoperated by Staecker (talk).It is used to make repetitive automatedorsemi-automated edits that would be extremely tedious to do manually, in accordance with the bot policy. This bot does not yet have the approval of the community, or approval has been withdrawn or expired, and therefore shouldn't be making edits that appear to be unassisted except in the operator's or its own user and user talk space. Administrators: if this bot is making edits that appear to be unassisted to pages not in the operator's or its own userspace, please block it.
This is the userpage of an inactive bot which was operated by User:Staecker from April 2007 to May 2008.
This bot's main function will be to place speedy-delete tags on duplicate image uploads.
The bot runs every 15 minutes and scans Special:Newimages. At the first pass, the bot just checks for uploads with identical filesizes. Any files with identical sizes have their thumbnails downloaded and compared directly (using PIL).
If the thumbnails are identical and the description page has no previous file history, then:
If neither version is orphaned, then neither image will be nominated for deletion, but both will be tagged with Template:Duplicate
If the thumbnails differ or the description page has a file fistory, then the images are logged to User:Staeckerbot/Suspicious images, to be handled by a human editor. I have found that most such cases do represent duplicate images, perhaps with different metadata or other differences invisible to the eye.
User:Staeckerbot/Suspicious images Images which were uploaded closely together and have the same file size, but differ as binary files. Many of these may be duplicate images, but need to be checked by hand.
User:Staeckerbot/Preapproval log (Feb 14 - Mar 13, 2007) A log from before my approval to edit- about 1000 recorded dupes, not marked for deletion by the bot
