I am 99% sure that is NOT Tracy.
This comes from a number of different angles, but primarily starts with my life experience with friends and family who either speak French as their native language, or as a second language in which they are functionally fluent, and for all of whom English is a second or third language.
Even with people who are well-educated and speak English at B2 or even C1 proficiency, there are always certain little tics and nuances ("tells") to their spoken and written words that are pretty easy to pick up on if you're someone like me who pays attention to those things. Common little "mistakes" like adjective inversion, assigning gender to certain words and terms, article errors (adding 'the' to things), contraction confusion, basic grammatical mix-ups, conjugation errors etc. are all pretty common; and when someone is wound-up or angry all of those things become far more exaggerated. For anyone new here, Tracy could get pretty animated when he was wound-up about something, and that is when English not being his first language became obvious.
Tracy's English is very good, even as a third language. Reading that most recent post above and some of the others since "he" returned, right out of the gate it's pretty obvious to me something is "off". The overall flow and sentence structure, far more accurate capitalization and punctuation, the kind of things that people don't change over the course of a few months and often years all seem to have changed pretty dramatically in less than a year.
To me, this is someone who spent a lot of time studying everything Tracy has ever posted and has been working very hard to mimic as closely as possible, but not very successfully imho (kind of like an Elvis impersonator who has a thick Bronx accent). My initial instinct as soon as they showed "back" up was that it's probably someone who knew and worked with him during the QSC heyday, maybe even had the password to one or two accounts, and who could convince the warehouse people who have been stuck in a holding pattern for months that he was the "real deal".
Someone recently suggested that the recent posts attributed to "Tracy" had a lot of signs of being AI-generated or at least polished, and I tend to agree with that. I doubt that Tracy would ever have the need or desire to run anything he says through AI, so again just another facet that convinces me this is all a grand scam.
The biggest tell to me is that despite being his largest audience and customer base, he hasn't shown up on MesoRx. Even if he couldn't access his account because of an id or password issue, he could easily contact one of the admins over there who would have ways to prove who he is who he says he is (or isn't).
Bottom line, NOT Tracy.
