I have been thinking that it would be helpful to list their history of previously managed campaigns and to clarify how many percentages they did the job correctly or were scammed. Some bounty managers, including most of them listed the above thread, has already disclosed their history by themselves, which I think is very nice, but not all of other bounty managers do this. When I was looking at campaigns managed by a bounty manager, some of them were scam but the bounty thread was simply locked by him. Not only does it block for the participants of that campaign to say anything more but also it seems to prevent participants of new campaign managed by him to aware of the previous scam. The list would be helpful for participants, and also encourage bounty managers to research by themselves to avoid managing scam campaigns.
