I don't think mold_time is a good example of citizen science done right. They have said multiple false things and refused to address or correct their statements when other people pointed them out. See https://www.lesswrong.com/posts/NRrbJJWnaSorrqvtZ/on-not-get... and https://www.lesswrong.com/posts/7iAABhWpcGeP5e6SB/it-s-proba...

It's been more than a year since I alerted them of the multiple falsehoods in A Chemical Hunger, repeatedly, and they haven't done anything about them.
