The terms for researchers examining potential violations of research integrity are bad (data police, data thug).

What is an alternative term that:

* doesn't imply anything about the intentions of the people who did the work being investigated (deliberate or accidental)

* doesn't imply the researcher has any power over the people/work being investigated

* does indicate the work is scholarly, and should be valued

* does indicate that "self-appointment" to investigate is appropriate & ordinary
