I backed several product campaigns that never amounted to anything. I understood there are risks, but indiegogo purports to mitigate those risks with contract terms that obligate the campaigns to deliver or refund. Despite thousands of requests from stiffed backers, however, indiegogo never enforces those terms and they don’t respond to consumer complaints. This company is a real den of thieves that, as a practical matter, is unaccountable for the sins it facilitates.
