This is a concern I have as an "anonymous" HN account, even up to putting it in quotes despite never revealing my name or strong PII. But the language I use as a reviewer is pretty different, even from that of a writer. I suspect this will be harder due to low sample rates but then again, high noise could help your point. Mobs need targets more than accuracy.

Though, we do eventually need to have a conversation about deanonymization of online accounts. That's not a thing we want to be done so easily
