If I didn't think it would expose me to limitless liability, I'd love to have a small business tying nooses and selling them to people.
I'd use only the finest hemp rope. The packaging would of course be discreet.
I'm not sure PayPal would be thrilled. Checks would leave a pesky paper trail.
There's always plain cash mailed. It's not foolproof, but it has less risk than other methods.
Wait. Am I talking myself into this? I don't think there's any good way to file taxes or to register this kind of business.
OTOH, cash in the mail is hard to trace.
Unless you post about your scheme in a social media platform.
