An international social network where one posts pictures/videos, write posts, has a profile, look at news, communicate through direct messages or group chats should be fully compliant with GDPR. Even across borders. Because consent for those activities is very explicit. What's not compliant with GDPR: Store cookies on a users computer, then let others look for that cookie and share the users data with them so they can target ads at you. Collect all that data from different site and create a profile of you that you then sell. You can also not move data out of the EU without guaranteeing to not do that.
