Non-free content use

Thank you for contributing to Wikipedia. We always appreciate when users upload files. However, it appears that one or more of the files you have uploaded or added to a page, specifically User:Amir.Vector, may fail our non-free policy. Most often, this involves editors uploading or using a copyrighted file of a living person. For other possible reasons, please read up on our Non-free criteria. If you have any questions please ask them at the Media copyright questions page. Thank you. -- Marchjuly (talk) 02:41, 18 April 2023 (UTC)

Please don't add any more non-free files to your user page. Non-free files aren't allowed to be used on user pages per non-free content use criterion #9 as well as per Wikipedia:User pages#Non-free files. If you're not sure whether a file is non-free, click on the file and check its licensing. If you're still not sure after checking the licensing, ask for assistance at Wikipedia:Media copyright questions. It's OK to make a mistake like this once maybe even twice, but you've had non-free files removed from your user page by bots or other users multiple times now. So, I'm posting about this on your user talk page just to further clarify things. If you've got any questions about this, feel free to ask them below or at the above-mentioned "Media copyright questions" page and someone will try and answer them for you. -- Marchjuly (talk) 02:46, 18 April 2023 (UTC)
