After a few tries on boring accounts, I thought to try the account of somebody who was notorious for an incident outside of HN, and had a (deservedly) bad time at HN for a couple of years before the account went dark. And yeah, there's a bunch of high confidence (.6-.8) hits for that account, and from a quick browse of the comments of the recently active ones, they look really likely to be alts. Like, all three that…
> quick browse of the comments of the recently active ones, they look really likely to be alts. Hmm isn't a spot check of comments somewhat tautological, since that is how the tool identifies alts (rather than something like IP address or time of day)? If this had been promoted as "find accounts with similar writing style to yours" would people immediately assume alts?
If some accounts are found to be stylometrically similar, and then a visual inspection also shows them all stating similar opinions, that latter piece of data is a strong signal.
