I see first time that they are openly managing bounty for commenting on bitcointalk.
Still admin don't think there should be
guidelines for bounty managers ?
They have now removed this bonus, but I noticed that the publisher of the “guidelines for bounty managers” is you, although it is a good suggestion, it is not an official rule of the forum and is not universally binding.
And they are aware of this problem before they can lead to large-scale spams, and they have terminated the BitcoinTalk Campaign in time, so I don’t think they have any faults.
In such a situation, should first communicate with their bounty manager, which may be a more gentle solution.
