I'm new to the api and this list, but I really appreciate that it's there.

I'm trying to create what I thought would be a simple query: "List all recent changes of all pages, but don't show anon, minor or bot changes"

In particular, I want the pageid, page title and userid associated with each change. Nice to have pre/post page size too. I've got the query working in my codebase, and on the wikimedia api sandbox: https://www.mediawiki.org/wiki/Special:ApiSandbox#action=query&list=recentchanges&format=json&rcstart=2014-03-04T00%3A00%3A00Z&rcdir=newer&rcnamespace=0&rcprop=userid%7Ctitle%7Cids%7Csizes&rcshow=!minor%7C!bot%7C!anon&rclimit=50

But even with what I think is the correct "rcshow" values, I still get anon edits - both in the sandbox and on the live site. 

In fact in some ways it seems like I'm *only* seeing anon posts. Any thoughts as to what's going on? Am I misunderstanding how the API works?

Thanks for any input!
