I think it sets a bad precedent and basically makes the tag useless. Now if you had active role in the day to day management that might be different but even then I don't think anyone has ever gotten a scammer tag without intent of malfeasance (i.e. just being foolish or naive isn't grounds for the tag).
That is for legally registered companies such as limited liability companies or corporations. It has nothing to do with general partnerships where all the partners are liable for all legal actions or debt that the partnership faces.
What partnership has shareholders?
Answer - none.
See the bigger answer above.
Corporations or companies with limited liability for their members, partners, or shareholders has not nothing to do with BitcoinGlobal. There is no limited liability for any owner, partner, or member of BitcoinGlobal. So I don't understand your argument that members of BitcoinGlobal are not liable for its debt.
