I think if SSB is ever investigated by the tax man, she will have a problem. I am not sure what the gift tax threshold is in France, but I am pretty sure she is over it. Moreover, I doubt very much if she is paying sufficient tax on her Patreon or YT income. I'm tired of the claims about the foundation, I don't see how they can pull that off... one needs to have a charitable purpose or be doing something for the common good to qualify.
She is also not allowed use Workaway volunteers for a business, and Selmar's situation with one client is illegal - he should have at least three clients.
As someone said earlier, SSB needs to watch out that she does not end up like Al Capone.
