After warning some users from the Spanish Wikipedia not to upload FAIR USE images to the commons (and blocked one of them...) I've checked the Wikipedia, and I've noticed that the UPLOAD FILE section in http://es.wikipedia.org/ leads DIRECTLY to http://commons.wikimedia.org/wiki/Special:Upload?uselang=es Uploading fair use images seems to be valid in any other Wikipedia, and the result is that the Es.Wikipedia users uploads the images directly to commons.
This situation CAN'T go on. Yuval
