My son's AAU BB team's account is suspended. The head of the program said that it was due to an algorithm that doesn't allow you to use other people's pictures and tweets (something beyond re-tweeting) beyond a certain threshold or it flags you. They apparently don't warn you either - they're still suspended. He said that they used graphics from tournaments to promote where they'd be or if they won etc. and the algorithm didn't like it. I wonder if it's something along those lines.
Or it could just be those Hawkeyes ...
