These managers are being lazy. Not checking the credibility of the project. The only thing in their mind was to make a profit out of the project in addition to their inexperience which put risk for everyone joining the campaign.
I agree, and I don't think a DT negative would even be a motivating factor, as some of these bounty managers are low-ranked members who could easily create another account and start the whole thing over again. You'll recall that what aTriz did got him a bunch of red trust, which basically forced him to abandon that account. That had an effect--that was a fairly well-established account that's now ruined. If a Jr. Member pulls the same shit and gets a neg, do you think that person cares? Likely not.
There ought to be a lot of things changed about the way managers run these bounties, and it'd be nice if there was a rank requirement for doing so. Managers put their reputations on the line right along with the project developers, and like it or not they're basically vouching for the project. They ought to have some sort of reputation to begin with to be able to run one of these bounties.
I would love to see you as a bounty manager boss because it seems to me that you are a very reputable member in this forum and any project that you will handle in the future would all be legit. Just my thought.
