Spooky, maybe. Retarded, definitely.

I have not, but we all know that people cycle Twitter accounts often.

Hmm maybe Luke’s alt account 😆

I had some IRC interactions with him years ago yes. (Under his pseudonym; did not know his real name back then.)

Very dry/weird sense of humor maybe ?

Never interacted with him AFAIK but it was my understanding back in the day that Luke transferred ownership of Eligus to someone operating under the wizkid nym. A possible explanation for those tweets is that Wizkid became salty about Bitcoin after Eligus became irrelevant.
