I know a lot about how the credit system works. This will NOT work, as authorized users available credit lines do not count towards credit utilization ratios, hence this scheme will only give a marginal bump at best. A better low-cost hustle would be to charge people to clean up their credit for them, then partner with a local attorney to feed him leads for a percentage for anyone whose credit was beyond repair, and need to file for bankruptcy.
