Cheating in bounties and Airdrops is not a good thing but most people in this forum do engage in such acts. these days most bounty managers require users to make an authentication post before you can participate in their bounties and I believe this is a good way to curb the rate of cheaters that participate in bounties and airdrops.
Not a good way to control scammers, because they have control of many accounts and WORKERS to manage them accounts. Scamming bounty is a new industry!! They can authenticate different accounts behind a VPN...
