On a similar note: This does not give me confidence in startups and "accelerators". Some (many?) startups will do questionable things for growth. They will upvote one another. They will give fake five-star reviews for one another. And they will call it growth hacking. I remember Reddit's "fake user" growth hacking.

The depressing thing is: Founders who want to play by ethical rules, will ask. "May be I too should engage in this behaviour, just to level the playing field".
