I personally would not recommend to them what methods they can use to deposit money.
1. You are directly proving that you are targetting a US audience.
2. You are aiding them is what could be construed as money laundering.
3. Free speech is a misnomer and doesn’t exist. What you say can and will be used against you.
4. For the record. I do not want anyone from the former land of the free to visit my website. It is prohibited for an american to visit any website owned by myself or companies I am affiliated with.
