In Spanish we say “música paga no suena”. Or “Paid music (service) won't play”. As in, if you actually want the DJ, Mariachis, or band to stay the whole party, withhold payment until the end. If you pay upfront they will arrive late and leave early. They already have the money on the bag, and no legally binding responsibility to actually deliver any product. Even with this new round of crowdfunding, tomorrow they could just claim they already delivered what could be done with the money and disappear into a fiscal paradise. And not a single chump who backed up this decade long fraud would have any single recourse to fight back.
