user-1: Should I VTC on species ID questions that have really bad image quality? For example, this post (no offense to the user who posted the question). 
I'm aware that I should first comment and suggest that they try to provide images with better quality, but if they fail to do so [since perhaps most of the time the OP can't so easily, or at all, revisit the organism] then should the question be considered unanswerable, at which point would govern a VTC? 
If so, what would be a reasonable, but not excessive, amount of time to wait before VTC? And if not, can you please explain why, since I myself would tend to think a VTC is permissible in this case. Thanks for your thoughts. :)

If the important image for an identification question is "unclear", then the question is probably "unclear" as well, unless of course the OP acknowledges that there is not much they can do about the image and they instead give a detailed description of what they saw.
So, I'd expect an "unclear" question to be closed as "unclear" so as to prevent answers based on pure assumptions. We don't want it to become a guessing game, I suppose.
And naturally, if a question or answer, in it's current state, is "not useful", then as the tooltip for the downvote button suggests, do downvote it.
