> What's to make them believe me now because I have some anonymous piece of paper.

I don't know anything about policework, but entering in a place illegally (I assume Jake or one of his friends doesn't have legal free reign in random German hotels) to intimidate someone into doing something is quite a thing. I could imagine the police caring enough to try to get fingerprints off of the piece of paper and perhaps come to the hotel room to check video footage and other fingerprints.

I'm not saying I don't believe you, but someone mentioned something that caught my eye as well, so I commented on it.

Up until now I hadn't doubted Jake's legitimacy. I also didn't agree with everything he said (having heard him speak and answer questions in multiple places, and briefly talking to him personally), but I figured it's just normal not to agree with everything someone says. Your article made me realize I should listen better and judge whether the good intentions are really there, and it made me much more hesitant when it comes to Jake and the Tor project in general (another comment linked an article with similar things about the Tor project as a whole). So thanks for sharing this.
