Suppose someone post a problem statement question so no attempts on the problem and it also happens that no one flag the question neither so it won't be on hold nor closed and somebody else (could be the same user that asked) put a bounty of +50 or +100,...
I notice you still have the option to flag the question, the thing is that would the question always remain as it is? or can be put [on hold] and perhaps the [closed] and hence no one can answer the question anymore?
for example like this question Maximizing the ratio of inner products
