I have known this source for about a year now. From the very first communication with him, he was VERY CLEAR that he had no problem AT ALL with myself or anyone else discussing him and his lab on the forums, provided they honored the requests above. TBH, if he would have said otherwise and attempted to stifle any discussion about his lab as a qualifier to being a customer of his, I would not have done any business with him.
@TruEnuff to answer your question about what I would define as "private", I don't really have an answer to that. It has become blurred and I haven't really given much thought to what a "private" lab is.
