I introduced the idea of a Pan-European Digital Stalking Response Protocol at the #32C3 Chaos Communication Congress, the biggest hacker conference in Europe (talk begins at 30.08 in the video)
There no simple go to place for real information wrt to protection and response to cases of digital stalking, but also the information needed is very country specific. However there are clear areas that need to be addressed, regardless of country, and we propose the creation of a Pan-European protocol on digital stalking which we will begin at a self organised session here at 32C3.
