Yeah this is really adding up to somebody abusing the kernel process. 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.)
