The campaign manager is not responsible whatever the negative things happen during bounty, he is also getting paid for managing the campaign. Even he is also one of the people like us, which he will research the basic things about the project and start promoting the campaign in order to get awareness about the project.
Correct statements. The managers who are well known here are known to have a good track record of the project they campaigned about and in most cases the project paid their hunters and participants as per discussed terms.
Often new managers hoping to get a job here, attempt to go with the shady projects but of they dont get paid up-front. From a project owners perspective paying the manager upfront is not going to be common, added the fact that 99% of the coin offering projects are failures from the start.
Still hunters should do their own research. Missing out things that could easily identify the project as scam is not a good thing.
