How are people supposed to donate Monero to Iran?

To who in Iran? The government?

People are generally not supposed to donate monero to Iran. The nation of Iran is not a charity.

If you’re in America, from your random ICE detention center cell.

Have you asked Monero before you decided to donate him?

This isn’t legal advice, but if you’re a US-ally you might want to look up whether your country has criminal charges related to supporting a terrorist organization. I know in the US, people have not only gotten years of jail but also had permanent residency stripped
