There is no researcher that is likely to use these forums for any type of data collection.

Knowing such data collection is banned by not only our community guidelines, but also the site's Terms of Use, makes such data collection both unethical and illegal. That means they could lose their job as a researcher, and be subject to a lawsuit.

I doubt any researcher would risk their career just for this kind of data (which, as Vibe notes, may not be all that helpful to begin with).
