Indeed. He seems to have obliterated all traces of his old name from Bitcointalk.

A quick search of BCT reveals only a single post referring to him as I remember him spelling it and mentioning ElDuderino in the same sentence.

Even a Google search only reveals  a thread misspelling it with an extra "o". Lots of mentions of other people with the same surname with a single "o". Only the misspelled one refers to BCT.

I thought that maybe it was a name change and not a new account.

Maybe the Dude can clarify the matter without too much of a breach of opsec.

Edit: He seems conspicuous by his absence. Hasn't posted in a couple of days. I hope he's okay.

I hope all those strenuous workouts on that proprietary exercise equipment weren't too detrimental to his health.
