I'm not sure if this is the right place to ask, but we have found a copyright violation on cy.wikipedia and have no way other than deleting the entire article to remove it from the history, which we would rather not do.
What is the approved method of getting rid of copyvios on small Wikipedias? Do we have to attract a developer's attention somehow? Just in case someone here is able to help us, the article in question is [[cy:Dewi Sant]] and we want to get rid of all versions from 18 February except the oldest.
