Да никак не скажутся, если вы конкретно не находитесь под санкциями или вас в список лиц, находящихся под санкциями не включили. Вот тут ясно написано "k. You are not subject to any economic sanctions or trade embargo (“Sanctions”), and you are not included in any sanctions list in the United States, the United Kingdom, Canada or the European Union, including, but not limited to, the List
of Specially Designated Citizens and Blocked Persons or the Foreign List
of Persons Evading Sanctions, Maintained by the U.S. Treasury Department's Office
of Foreign Assets Control ("OFAC"). You
must notify Shutterstock immediately if you become the subject
of any sanctions.
You have no right to publish your portfolio in a way that distorts the nature
of your relationship with Shutterstock."
А если вы попали под санкции, то вам предлагают уведомить их об этом.
