Day by day people are getting to know crypto currency, each day good number of interested people join the BitcoinTalk forum. The way the bounty qualifications and rank was in 2012 is not any more. Getting to the next rank is getting more difficult,KYC came in and many other changes, Now don't you think very soon most signature will only be opened to people from Full member and/or very few number will be given the chances of participation in many bounty campaign to have it convenient?
I believe you know Bounty Campaigns are form of marketing. So basically, it hovers around the best decisions need to make a bounty campaign more fruitful. If reaches and desired results are not met in the future, the campaign organisers and custodians like bitcoin talk can make changes to bring desired results. This are is not may worry as long as it doesn't decimate bounty campaigns by crypto projects
