You have uploaded multiple non-free images under invalid licences, which is a sign that you have not understood our licencing policy. Uploading files that have to be deleted creates a lot of work for other users, therefore you have been blocked indefinitely.
This is not a sanction, only a way to prevent you from doing something harmful. The block will be lifted on your request, provided you give a written statement that you have read, understood and accepted our copyright policies.
