I agree. A great example of why can be found in this excellent article about an extensive "dossier" of fraud allegations against a top Alzheimer's researcher: (https://www.science.org/content/article/research-misconduct-finding-neuroscientist-eliezer-masliah-papers-under-suspicion)

Specifically, this snippet:

"Microbiologist and research integrity expert Elisabeth Bik, who also worked on the Zlokovic dossier, contributed other Masliah examples and reviewed and concurred with almost all of the findings."

Elisabeth Bik is someone who has an incredible eye for fraudulently edited Western Blots images and someone I greatly admire. Calling her a "research integrity expert" is accurate, but what I find neat is that (to my knowledge) she doesn't have any particular training or funding towards this work. A lot of work she does in this area starts on, or is made public on PubPeer, an online forum. This is all to say that Elisabeth Bik's expertise and reputation in this area effectively stems from her just being a nerd on the internet.

I find it quite beautiful in a way, because she's far from the only example of this. I especially find it neat when non-scientists are able to help root out scientific fraud specifically through non-scientist expertise. As a scientist who often finds herself propelled by sheer enthusiasm, sometimes feels overwhelmed by the "Publish or Perish" atmosphere in research, and who worries about the integrity of science when there's so much trash being published, it's heartening to see that enthusiasm and commitment to Truth still matters.
