Hmm, it appears that they relied on the quality control of forum moderators but didn’t do any of their own QC? From the methods section: > The database of drug narratives from Erowid’s “experience vault” is entirely anonymous.

By means of that mechanism, all reports that provided the basis for the present investigation have successfully exceeded a standard quality filter.
