but bounties are not giveaways.
bounties are kind of short term/micro jobs . we offer some rewards to users to perform specific tasks/jobs for us.. I don't think it should be called a giveaway. nothing is being given away for free.
Bounties is very broad term which includes certain activities and tasks which you undertake like Facebook Like/Share/Comment, Twitter Like/Retweet, Blogs, youtube, Articles, Signature Campaign on Bitcointalk etc.
Excluding Signature campaign all others are external activities which are not undertaken on bitcointalk thread and thus help in controlling the quantum of posts and messages (SPAM) under each thread.
That's why comment on ANN or specific thread in not considered as bounty as per rules because it will increase spam and unnecessary or unrelated post. Moreover the use of Bounty is to increase awareness regarding certain projects for general masses so the comments on ANN thread doesn't really help in doing so as it might be flooded with fake post which might create a good/bad reputation for that project.
