I was curious about this, my highest match was 0.47 and I have no alts, maybe I'm also a unique snowflake, or haven't said anything noteworthy enough to have been deepfaked yet ;).

my second highest hit (ie, third in the list) is gwern at 0.45 who i'm fairly sure is not me.

I was actually just looking at near hits for gwern and found what's almost definitely a defunct alt for him.

Well is certainly NOT me, that's for sure.

On an unrelated topic, I'm starting a service to write comments in the style of others to provide plausible deniability for other alt accounts. Rates negotiable.

I have a few in the low 0.5's and, honestly, they seem cool and I want to meet them.
