oDesk is a system where people can offer or take jobs. Wikimedia uses it (though in a somewhat different way). How on Earth do those two facts imply "oDesk is probably used for paid editing"?
I'm not sure "probably" is necessary. The evidence strongly suggests that it _is_ used for paid editing. Whether it's used for paid advocacy is another matter, of course.

I think oDesk serves multiple functions. The Wikimedia Foundation is apparently a client, but individual Wikimedians have also apparently been posting "hire me to write an article for you" entries.
That said, either oDesk's search functionality is terrible or the practice doesn't seem to be particularly common. I've only found a few "Wikipedia Expert" or "Wikipedia Writer" listings off-hand.
