in all seriousness though. one could start (lol using a crowd source), a website that unofficially regulates and takes in reviews and ratings on crowd sources themselves.
fake bullstuff exists like that that pretends to be legit, to trick consumers into thinking you are the safe place to go for info, when you are really just taking in money and controlling how other products that have nothing to do with you are sold.
they call a few of these organizations: ESRB, BBB, yelp... corporate owned "services" that just hijack the industry :p
make one that "regulates safe and fair use" of crowd sourcing. $$$
make people pay to get their CS listed as you arnt stuff unless you make the site. make people pay to get bad reviews/complaints removed, make people pay to give ratings. ironically taking in money to counter seller/consumer back and forth. ad money as well.
