Not sure how Tesla could "cancelled process to it being posted on TMC". TMC doesnt have any relationship with Tesla itself. Yes, they do have people who look at social media posts here and elsewhere, but I doubt that the registration (that was stated as being posted on behalf of a relative) had the name "nutterbutter" on it.
There would be no way for them to tie it to the family member you mention you posted for.
They dont allow it though, so Im not surprised they canceled it, but I doubt seriously that your specific reservation was canceled because it was posted on TMC.
