Bulletproof hosting refers to hosting services that resist takedown requests, abuse reports, and legal pressure to remove content or terminate service. The 'bulletproof' label comes from the idea that the hosting is resistant to the standard mechanisms used to shut down internet services - DMCA notices, abuse complaints, law enforcement pressure.
True bulletproof hosting requires operating in jurisdictions where foreign legal instruments like the DMCA have no binding force, maintaining enough legal and operational independence that a single pressure point cannot take you offline, and having explicit policies about what abuse reports trigger action and which do not.
It does not mean hosting that enables illegal activity targeting real victims. AnubizHost and legitimate bulletproof providers prohibit content that causes direct harm - spam, malware distribution, child exploitation material, fraud. The 'bulletproof' protection applies to content disputes, copyright claims, and politically-motivated takedowns - not to harmful criminal activity.
