Bounty board has this pinned post:
https://bitcointalk.org/index.php?topic=2103690.0"Incentivising posting within one or more threads is not allowed"
Also quoting from:
you can't give people any bonus for replying to your thread.
Yet some bounty threads have requirements like these:
Join the Facebook bounty campaign by liking our Hyde & Co. Facebook page, and commenting in our
Announcement threadSo before I go on a report-to-moderator spree - is this kind of bounty spam allowed?
That was the thing that used to happen, but some time ago the regulation moderation has been updated. Doing or ordering to comment on the thread announcement of a project is not allowed, it is because to avoid spam by bounty participants. Especially if it is clearly written and the OP obliges it then it is the wrong action.
Now many campaign managers who have a good reputation have applied the rules, for example yahoo who always say "Helping bump the Announcement thread would be appreciated but not required".
You can take action in accordance with the rules and I think you are on track to improve the quality and contribute to this forum.
