Although keeping to rules in this context is NO because they will always write that; we reserve the right to adjust the rules now or after. With this particular clause, they can act strange after the bounty end. These are their tactics to eliminate many hunters from getten their tokens after the campaign. Have worked with different projects and found out that, many of them want free advertisements from gullible bounty hunters.
This is the current dilemma. This situation cannot be compared to previous years, especially in 2017 where all aspects of cryptocurrency reached its peak, many successful projects without drama, thus bringing a positive impact on the bounty. The opposite is happening right now, many projects fail and don't reach their targets because of the bad season, only some of the bounties are truly successful, the rest always ends in tragic drama. Well, we have to understand that as a risk.
Rules are rules, like it or not we have to obey them. So it is important to choose a competent bounty manager so that it is not easy to change the rules without regard to the bounty hunter's rights.
