Unfortunately during the campaign we saw that not some or most but all of the bounty users that registered were just providing useless spam on all channels and low value content that did not translate into any meaningful interaction around our project.
Hmm... What do you expect when you hire people who look to donkeys for advice?
Bottom line is you can't just promises huge prizes and then just abandon the entire bounty no matter how bad it is. Granted not even your best posters "deserve" big payments, but what does it say about the character of your team if they make promises and then turn their back on them?
