Oh, now I remember again why we kicked these guys off the premises. They're basically a right-wing russian propaganda outfit ... unfortunately, we can't stop them from filming anyone on public grounds.
State propaganda, to be exact. They are a subsidiary of Russia Today ("RT"), which owned by the Russian state via RIA Novosti. Ruptly mainly provides (uncommented, but suitably edited)
war propaganda the Russian point of view on conflicts between Russia or its neighbours and other states, as well as reports about the supposed decadence of "the West".
They pulled the very same stunt at Anthrocon this year, by the way.
