Unfortunately, many of those languages don't have sysops who can delete the page.
Might be. Hoewever i took the list of the different versions and visited all of the language versions yesterday. In 38 language versions i made Deletion-Requests (where i could find the template, it might be a good idea to make {{delete}} available [as a redirect] in _every_ wikipedia) or left a notice on the feedback/forum/cafe/whatever. It seems that many have already acted upon it.
In 11 more language version the article was already deleted or someone else took care. Only in 5 languages i could not find any way to notice the admins: br, io, iu, th and yi.
In the meanwhile some anonymous user from Estonia showed up in the VfD for [[:en:Tony Blackplait]], the alledged frontman of the band which articles contains lists of movies and books who can't be found in catalogues. He/She claims that there would be truth in the article and argues that mistranslations had occured. I still don't believe that, but there might be some more truth in this entries than we first thought. However it seems that the criteria for relevance won't be reached anyway so it does not make a difference.
