Used to see them doing this all the time at Marin & Columbus.

Has anybody ever had someone knock on their apartment door, identifying themselves as working for LIBERTY ENERGY?

He had a brochure and ID, saying that they are a clean energy source and are taking a survey to see if I would like to switch.

I live in an apartment building, so someone had to buzz this guy in. He was an Asian gentlemen, probably in his late 40s or so.

I'm assuming it's a scam, right? The company does exist, I googled it.
