Yes, probably some kind of statistical analysis is required

Mm, a few dozens perhaps, so not that big of a collection, although I
could collect more of them...
Technically, one could just crawl the Net using a search engine. Google
now shows 120.000 hits for filetype:odt, for example, but I'm not sure
how this works out legally (some websites don't even want you to link to
them...)
It should be OK I guess, but I'm not a lawyer...
But it would indeed be easier than uploading the documents: that way you
won't have to worry way less about uploading sensitive documents.
Best regards,
