Sometimes they make KYC mandatory in the end, after not mentioning about it in the beginning. And sometimes, they extend the duration of the campaign, without increasing the bounty pool proportionately.
Yes, I often see bounties like that, for example Mycro Jobs at the beginning of the bounty was launched. They did not say that following the bounty, they had to do KYC, but after the bounty ended up to 1 year, the manager said that he had to do KYC to make sure when the distribution was right on target. disappointed that the allocation of prizes was cut even though the campaign was extended.
They should add allocated funds for the bounty for extra promotion they do for extending the campaign not reducing it and adding a rules with KYC. They are making it difficult for promoters to claim thier payment .
