The contractor lead-platform economy runs on volume sold as quality. ContractorTalk and r/Contractor threads document the pattern: providers charge $25-$65 per lead for incoming inquiries that turn out to have wrong numbers, never respond, or ask for services the contractor does not offer. The same threads also document Angi's 1,800+ BBB complaints around the "Angi credits" forced re-spend model that refuses cash refunds. The contractor pays for the lead twice: once in dollars, once in field-team time wasted on a no-show.
