Stopline
Stopline, initiated by the ISPA in 1998, is the officially authorized online reporting centre against depictions of sexual abuse involving minors and evidence of endorsement of National Socialist ideology on the internet. Here, users can report pages containing such content - even anonymously.
The Stopline team examines these pages and works closely with the providers and law enforcement agencies to ensure that illegal content is removed from the network.
