I started a bounty to bring attention to my question Why did Romero cast a Black actor as the lead?
The bounty mechanism allows for bringing attention to a question specifically.
Now am am being accused of "ulterior motives".
Let me explain first the motive of bounty.
From Help Center page for bounty(emphasis mine),
If you’ve asked a good question, edited it with status and progress updates, and still are not receiving answers, you can draw attention to your question by placing a bounty on it.
You can also choose from a list of bounty reasons to help other users understand why you’re dissatisfied with any current answers to the question. If you need to describe something in more detail, there’s also optional, additional custom text that will be displayed with the bounty reason.
Here is the list of bounty reasons from the blog.
Authoritative reference needed
Looking for an answer drawing from credible and/or official sources.
Canonical answer required
The question is widely applicable to a large audience. A detailed canonical answer is required to address all the concerns.
Current answers are outdated
The current answer(s) are out-of-date and require revision given recent changes.
This question has not received enough attention.
The current answers do not contain enough detail.
Reward existing answer
One or more of the answers is exemplary and worthy of an additional bounty.
It's clear that you can start a bounty to get or award good answers.
The reason you have put for the bounty was
A bounty to draw attention to the need for this question to be closed and deleted. It's obviously bad due to the downvotes received.
This is not the valid reason. You can't start a bounty to get your question closed and deleted even when it has a good answer.
