Generally for the eu: https://www.europarl.europa.eu/doceo/document/E-8-2017-003934-ASW_EN.html “If users receive unsolicited communications after having withdrawn consent, they can file a complaint with the national regulatory authority. In addition, they have the right to a judicial remedy before national courts.”

Apparently Denmark is leading the pack with 1.83%, closely followed by the 3 Baltic countries. Poland is 7th with 0.68%. The usa is “only” at 0.35%, which is still by far the most of any of the non european nations that have send help, and also significantly more than a bunch of eu nations.
