In Finland, organizations seeking to carry out donation drives (charities etc.) must seek permission from Finnish police. The measure is intended to make it more difficult to carry out fraudulent donation drives in the country.
Since Wikipedia's fundraising activities on its Finnish site technically qualify as a donation drive - at least according to letter signatory Jouni Laiho - the Wikimedia Foundation should have sought approval from the Finnish Police Ministry in advance.
I dunno what that is.
I guess every website in the world that has a donate button had better start asking the Finnish police for permission!
