There is a question on Stack Overflow which suffered from offered bounty a lot.
In its normal state there was a passer-by with silly answer once a week, but with bounty attached it attracted them every day (these silly answers gets eventually deleted - so, you need enough SO rep to see them).
Is there a way to take a pointless bounty out? And also, is there a way to raise a protection threshold to at least 100 points of reputation? This question is still of current importance. One "sympathy upvote" opens you door to any "protected" question but it doesn't prove your knowledge or experience at all.
