![]() This media file has been nominated for deletion since 24 August 2024. To discuss it, please visit the nomination page.
Do not remove this tag until the deletion nomination is closed. Reason for the nomination: Another batch nomination for deletion of 81 files uploaded by indef blocked user:Claudio Pistilli. Problems are the same like in previous batch nominations: 1, 2, 3, 4 or 5. This user has been posting on Commons for many years what he produced on eo.wiki, where there is no real moderation (77 active users last month) and no one to stop such problems. He created chemical illustrations apparently without the required competence in the field.
On the one hand, 2D graphics are created as if from children's books, without considering the existing global, independent of Wikimedia, IUPAC recommendations from 2008 in this field. His illustrations are practically unusable anywhere. Additionally, there is the problem of mixing together parts of different illustrations, which results in graphics containing different styles, fonts and colors. In some cases (chemical reactions), it turned out that the sources did not confirm the course of these reactions. On the other hand, we have 3D models, for which he used models already existing in Commons, miing them together in a way that generated problems with the appropriate sizes of atoms, the correct geometry of the molecule. At the same time, he did not provide any information about the files he used, so any file created this way is a potential licence violation. At the moment, none of the files listed above are in use, many of them already have existing replacements. | ||
