No, we assign the studies weight based on their design, not on their conclusions, not on their source, not due to what floating around on social media at any given time.

It's good to know that you don't even have a clue how the regulatory agencies determine the exposure limits, as we bake a safety factor right into the development of the ADI, and similar metrics.

We start with the experimentally derived aggregate NOAEL, then apply a safety factor to account for the use of an animal model, along with the variability present in the human population.

I'd normally write that you should take a step back and actually learn some toxicology, but your ramblings are far more amusing to poke holes in.
