I found the answer of my question in this link :
The Services are subject to the trade and economic sanctions maintained by the Office of Foreign Assets Control (“OFAC”). By accessing the Services, you agree to comply with these laws and regulations. Specifically, you represent and warrant that you are not (a) located in any country that is subject to OFAC’s trade and economic sanctions, currently Cuba, Iran, North Korea, Syria, and the Crimea region of the Ukraine, or (b) an individual or entity included on any U.S. lists of prohibited parties including: the Treasury Department’s List of Specially Designated Nationals List (“SDN List”) and Sectoral Sanctions List (“SSI List”). Additionally, you agree not to – directly or indirectly – sell, export, reexport, transfer, divert, or otherwise dispose of any service received from DigitalOcean in contradiction with these laws and regulations. Failure to comply with these laws and regulations may result in the suspension or termination of your Account.
I hope US government focus on our regime not on people and Be omitted sanction against Iranian developers
