Hello Sara,
According to the following presentation of "The Spamhaus Project" - they receive massive amount of illegaly obtained private data of internet users from internet companies and internet organizations and then they share it with LEA's like you (in illegal way
without any warrants).
The European Union have very strict privacy laws, this kind of operation is very very bad and violating the privacy laws in your own countries.
Is that the reason that people behind "The Spamhaus Project" are untouchable and complaints regarding them are ignored ? because they share massive amount of privacy data in illegal way (without any warrants) ?
I have more presentation that I'm interested to share about that whole massive privacy violation scandal if the community will show interest.
Respectfully,
Elad
