Michael, I appreciate the concern, but speaking as the esteemed OP ( :MILD: ), I'm happy to have Juboy contributing to the thread. I know him to be a decent guy whose opinion I respect, and as far as I'm aware he has no personal commercial interest in promoting Auralex, so I don't see any reason why he shouldn't be allowed to contribute.
Obviously, as ZeroGain is your baby the final say is yours, but I just thought I'd put in a good word for Julian.
