Hi Anatoliy,
 
I think there is little we can do about this, aside from informing you and being alert about the upload of non-free media on Commons, which is nothing new.
 
Assuming that your representation of events is correct, it appears to me that the way "Fair use" has been implemented on uk.wikipedia may be in violation of a resolution of the Board of the Wikimedia Foundation[1]. I would advise you to review the document I linked below and analyse if the current policy on uk.wikipedia is in occordance with the Resolution.
 
If you require specific advice, this mailing list could be a platform for discussion. I have no opinion on the internal matters of uk.wikipedia; as long as the community wanders within the boundaries that have been set by the Foundation, I think the community should find solutions for their own problems, or, if involved parties agree, request mediation.
 
Personally I am against Fair use in any project of Wikimedia, just so you and others know what would be my POV.
 
Cheers! Siebrand

Onderwerp: [Commons-l] Ukrainian Wikipedia

I propose forbid uploading images from Ukrainian Wikipedia, because uk-wp admins abuse copyright. Some of them uploads non-free images with free licence. Other ones use fairuses in templates and userpages. And you may upload ANY image and put license {{Fairuse in}} and image will stay on Wikipedia during months.

Last week some sysop (Turzh) uploaded many images with license CC-BY-SA from the site sobory.ru , but author allows only non-commercial usage (see OTRS ticket#2008070810020169). I ask that sysop to delete these images because such permission is unappropriate but he continued upload images. Today I ask him again to delete it (because images with free license maybe uploaded by any user to Commons; and I as Commons' sysop care about purity of project), but he said that he not uploaded it in Commons, it is uk-wiki, and he does what he want. Then I put templates {{db}} to some images but he blocked me for 24 hours.

That's why I suggest to forbid uploading images from uk-wiki (firstly via CommonsHelper and then with another ways) without admin review.
