AIAA has a Social Media Policy! Many committees (along with regions, sections and branches) have "unofficial"-official AIAA pages on Facebook, Twitter, etc. The policy isn't meant to be a set of rules that would constrain activity on those pages; it just outlines what the Institute would consider to be inappropriate content for an AIAA-branded page and explains what to do in the case of a hack or account compromise.
