Can I participate in the leader board?

Hello, I’m from Bulgaria and my question is can I participate in the challenge’s leader board because the footer in FastMRI says:

NO PURCHASE NECESSARY TO ENTER/WIN. A PURCHASE WILL NOT INCREASE YOUR CHANCES OF WINNING. Submission Period begins September 5, 2019 at 12:00:00 am UTC and ends September 19, 2019 at 11:59:59 pm UTC. Open to legal residents of the Territory, 18+ & age of majority. “Territory” means any country, state, or province where the laws of the US or local law do not prohibit participating or receiving a prize in the Challenge and excludes China, Kenya, Argentina, Cuba, Iran, North Korea, Sudan, Myanmar/Burma, Syria, Zimbabwe, Iraq, Lebanon, Liberia, Libya, Somalia, Zimbabwe, Belarus, Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Kosovo, Montenegro, North Macedonia, Romania, Serbia, Slovenia and any other jurisdiction or area designated by the United States Treasury’s Office of Foreign Assets Control. Void outside the Territory and where prohibited by law. Participation subject to Official Rules . See Official Rules for entry requirements, judging criteria and full details. Winners are invited to attend & present at the Medical Imaging Meets NeurIPS workshop in Vancouver, CA on December 13 or 14, 2019. Winners are responsible for all costs to attend workshop/conference, including conference registration fee. Sponsor: Facebook, Inc., 1 Hacker Way, Menlo Park, CA 94025 USA.

Unfortunately legal residents in Bulgaria can’t participate. This can’t be changed due to the ongoing nature of the challenge. You’re still welcome to submit to the public leaderboard to see how your reconstructions compare.

Thanks,
Tullie
