I'm not saying that "Russian Bots hurr durr". But political activists do use bots. Even the alt-right. I would be surprised if there were some bots there.

At the same time, it is fucking HARD to grow traffic organically & rapidly. It wouldn't surprise me if Bots were being pushed to drive people to the site, the same way political agitators are sent into tense areas to organize people into larger semi-organic protests.
