If you called him on it he would say that was on purpose, then talk your ears off about how. He was a ferociously effective charlatan, which is why people still remember the name he made up for himself. (And even invented a rhyming couplet to prate as a pronunciation guide!)

These don't sound like convincing indicators of being an "effective charlatan". Am I to see the Notorious B.I.G. in the same frame?

You are delusional.
