Best way to stop multi accounts, what do multi accounts want, they want to open new accounts so they can start over with legend/master talents and course knowledge and be able to tee off from short tees using best equipment to clean up matchplay challenge and ready go's.
Simple, remember the phrase "if it isn't broke don't fix it"? well a few years ago, WGT had a simple old system when you leveled up to a new tier, the equipment for that tier was then unlocked. So a pro would find bethpage extremely difficult playing from pro tees but with 245 yard driver so people WANTED to progress to unlock the longer/better equipment. So a pro wanted to become master so they could get the LONGER driver,
Revert back to this good old trusted system, and multi accounts would diminish as why would you want to go back to hack tees and get stuck with 225 yard driver!
