I was thinking of starting this kind of service, but I got scared by the potential liabilities and legal issues of giving a person basically a second identity. How would this work for hotels and stuff? Do you basically make a fake company, open a bank account in its name, and use that account to buy stuff discreetly? What if the person you a proxying for bought something illegal with the account? Who’s liable?
