There are many people with multiple DUPR profiles, and we have easily confirmed this by seeing that locations, names, events played and even the partners overlap. It is an impossible coincidence that 2 different people would have the same exact name, and would play with the same partners in the same tournament. And then these people use the DUPR ID with the lower rating to register for the tournament so they can play down and win. And then the tournament Director logs the scores with the ID with the DUPR ID the cheating player submits (their 2nd DUPR ID with the lower rating) so then if you lose to them, your rating gets tanked, but even if you win against them, your rating doesn’t go up much because they have an artificially low DUPR due to their multiple accounts. DUPR should “verify” accounts with birthday and photo ID and force merge accounts if / when this is reported. Otherwise the DUPR rating is simply not legitimate or reliable. It would be very simple they can sort all players by names and find duplicates, contact players and verify. And they could research when incidents are reported and take swift action. This is the only way that credibility can be built and maintained on this platform.
