forget about the last active or any other status, it ca be as irrelevant as it is ! , you can find tons of similarities between theymos and newbies  for that matter.

quoting the signed message is indeed sketchy.

looking at the "Xal0le" last post on "stak your btc address" (August 24, 2018) " before the deleted post"

and when this happens only 2 minutes after the account was created , it get's more sketchy.

but the funny thing is, why would he sign a message with his alt? it's a newbie account that worth nothing, why bother stake his address then quote it?
