The mental image I'd have of a Russian Troll House would be something luking in the boreal forest in an area where the ancient Scandinavian Rus had installed their camp, with the malificent troll in someone's kit bag. It turns out that the Russian Troll House is located in a banal office building in St. Petersburg, and has trolls working shifts grinding out reams of copy about Ukraine, the prowess and manly charms of Putin, as well as recipes and sporting news to attract and enthral the Internet masses. http://www.theguardian.com/world/2015/apr/02/putin-kremlin-inside-russia...
There are doubtless other troll houses, from various agency or lobby groups, as well as private commercial interests. But none have shown much interest in rabble or babble. We had a knot of hardcore Zionists several of years ago, but they seem to have all been ... Canadian Zionists, at least one of whom had several sock puppet identities.
Do they lurk in houses on chicken legs, like Baba Yaga's? And will Magoo slay the offending house, and cook up the legs in his smoker?
