Well that's really helpful of them.

I've updated the link, can you read it now?

Edit: FWIW, this was on the first page of Google for me - in Poland - when searching "paypal file-sharing"

Thanks, the link works now for me.

Apparently this depends on the country. Your link includes JP for Japan and the contact mail address for Japan (which ironically is spelled wrong).

I really cannot reach it from Germany without this ?country.x=JP.
