So to followup the experiment: I checked Google Analytics now and was surprised to see that after I added the English warning, late May—early June 2012 saw a big spike in traffic from the German Wikipedia to the DNB FAQ, many times the daily average. Presumably this must have been from some article in the German media on dual n-back.
Unfortunately, the data ends at 10 June 2012… because that was when I moved to Amazon S3 to save on hosting costs, breaking all my existing redirects (Amazon S3 doesn’t do .htaccess or redirects) - and the German article was pointing to a redirect. D’oh!
Anyway, there’s no obvious sudden drop on 20 May 2012, but the big spike contaminates all the relevant days.
I guess I’ll wait another ~100 days and see what happens now that everything should be working properly...

Update: traffic has still not recovered: http://dl.dropbox.com/u/85192141/Analytics%20www.gwern.net%20User%20Defined%2020120131-20121130.pdf
I infer this means the English warning is indeed deterring a lot of traffic.
