The deplatforming of legal firearms content has accelerated following pressure from payment processors and financial institutions. Shopify banned firearms sales. Stripe refuses firearms merchants. Mainstream hosting providers have followed payment processor policies by declining firearms-adjacent content even when entirely legal.
This deplatforming is based on merchant risk policies and advocacy pressure, not law. Selling legal firearms, parts, and information is legal in the United States and many other countries. Bulletproof hosting providers in Romania and Iceland have no relationship dependency on these payment processors and evaluate content based on law rather than payment processor policy.
