I think tagging Newbies for "bounty abuse" is futile. Accounts with high Activity and 0 Merit have nothing to lose, because they can easily create new accounts. Worse: it makes negative feedback very common instead of reserved for scammers, which leads to more and more people (including bounty/campaign managers) ignoring the warning. So I don't think tagging them makes the forum better.
Nice to see you're beginning to understand the problem. You still have a ways to go, but I think you've reached the opinion I had in about 2016. Maybe in another half a dozen years you'll start to see that you're actually contributing to the problem and begin working to fix the trust system instead of trying to empower those who are actively destroying it in order to maintain some form of control even though their lack of actual interaction trading and working with users makes them unfit to carry such responsibility.
