If he was still using the pseudonym and making excuses to keep using it, sure, but I’m of the opinion that once someone understands what they have done wrong and took the opportunity to learn from it and do better there is no more wrong doing. There are, of course, exceptions to this, but a pseudonym that someone came up with in their 20’s and had the wherewithal later to say, “That’s not ok, I need to stop doing that” and stopped doing that for the right reasons is pretty far from a reason to call them problematic, especially when it wasn’t a decision made under any form of duress and he has made no attempt at defending his choice to have used that pseudonym and stated it was not ok for him to have used that pseudonym.
