They say they’re MLs on their patreon:

We make videos of us sneaking into places, breaking laws and kissing each other, all for the purpose of spreading the immortal science of Marxism-Leninism. We’ve got some very big ideas in the pipeline, releasing some very ambitious documentaries and we need your help to get them done. Since a lot of the world’s political issues are quite visceral and confronting, Youtube often makes it hard for us to publish our work. As Boy Boy patrons, you’ll be helping us get these videos out to the public without worrying about censorship or demonetization.
