At the moment, it's sales and trading of firearms which includes BB guns by their default. Whether it impacts on airsoft (non second hand sales) and photos of military stuff remains to be seen.
Facebook is useful in that many people have access and its really easy to post stuff up, especially photos.
However, if FB get very silly, we will just start up websites and fan forums to cover what we do and general milsim activity. At the end of the day, FB is just a type of social media which has been convenient to use.
Our sister organisation, Gunman Airsoft already have a website and forum running in parallel to their FB activity.
