@ophiocephalic great pointsl. @rwg and @rra 's https://www.cell.com/patterns/fulltext/S2666-3899(23)00323-9 has best practices for researches on fedi, and goes into detail on the expectations of privacy and history of poor research.(Of course, fedi is not monolithic, and the norms on Lemmy quite possibly do assume consent. But it's more complex than that: Mastodon posts, from peoiple who aren't consuming consent, can federate to Lemmy, so get swept up in this.)Also worth mentioning: Google's Perspective API also has known racial biases - see https://civic.mit.edu/index.html%3Fp=2402.html for example.
