I think 'Josh Law' or any other pseudonym that can be traced back to whoever's behind this should be banned from the mailing list altogether. Also, as per Christian ([3]), it seems this guy was using the pseudonym "techyguyperplexable". There's a github with the same name ([4]), and that same user made a comment on an openclaw issue relating to linking it to gemini ([5]). So it seems likely he/she is likely using openclaw to fully automate this 'Josh Law' user and we're speaking to a bot here. (Screenshots have been taken for the (possibly inevitable) deleting that will happen later.)
