I'm not sure about the correct approach to RD, by whatever name he uses. (He transitioned from RD to Rompers with Heartbreaker.) For the purpose of avoiding distractions to discussions, ignoring him, by whatever name, is certainly best.  As Christians, we should have sympathy for someone who is clearly troubled, but, on this forum, I do not see a way of helping him and, again, think ignoring him is best.

As to showing off, Romper's Spanish is sometimes not grammatically correct (e.g. esto es en... rather than esto esta) and certainly is not idiomatic.  It impresses me only as to what a sad case he is.  I hope he will find appropriate help and also hope everyone will join me in praying for him.
