A lot of people had made complain on the rule for the bounty even in the telegram page, some of the complain led to the change of duration from 12 hours to 4 hour. I feel the 4 hrs difference is very good compare to previous, the campaign have very few signature participant and they seem satisfied. Spam post in this period does not deprive in any form
If only two posts daily, four hours gap is attainable but if three then we have a problem, bounty manager should have no time restriction that long the most important thing is the posters are not spamming and they contributed on various topics.
