The galling thing to me is that these "lifetime bans" do nothing to stop scammers because they can easily create dozens of new companies and identities to continue ripping people off with. For them, it's just a cost of doing business. Either through legal or illegal means, scammers find a way to create lots of different companies and manage to get back on these platforms after their first efforts are "banned for life".

The only people who are actually banned for life are normal well-intentioned people who get their fledgling small business destroyed and don't think they have any recourse.
