At present one person can use multiple accounts in Bounty camp in but it was not like this before so is the quality of our work decreasing day by day I request moderators and those who are in higher position to control this work
I am not sure if you are a bounty manager or if you are relying on a bounty manager. I hardly believe you are a bounty manager with three activities. If I am not wrong, multiple accounts were allowed to register in the forum from its start. It's up to the campaign manager whether he will allow multiple accounts. It's his responsibility to check if someone is enrolling with multiple accounts. Back in the old days, theymos had to add a scammer tag manually if it was proven that someone was a scammer. Cheating in the bounty campaign is a scam as well. Since implementing the Trust and feedback system, theymos removed the scammer tag from the forum. Choose a reputed bounty manager who will check multiple accounts. This is not the moderator's Job.
