TL,DR: me too.
Posting a scan of the text in a textbook or worksheet is a low in laziness. (I'd say a new low but I've seen that before on SE.) That right there can justify a downvote.
A scan of a figure can be ok, as long as it has accompanying text that explains the problem. For example, this is an appropriate question:
the text in book reference says ...
Frankly, this is what teachers and teaching assistants are paid for.
You can also ask peers or more advanced learners you trust.
Reviewing material is generally a bad fit for this platform: it's a task that requires lots of reading (as opposed to a snappy, self-contained question) and has no clear-cut answers.
You may also want to consider carefully if ...
First of all, if we would like to have a specific rule against such questions, I don't think it is useful to make the topic "P vs NP" part of that rule. I don't believe we are being flooded by questions about that topic and I don't think that that topic is inherently
'problematic', nor that it is within the domain of research. (That is, questions ...
I sympathize, and I understand how it can be demoralizing to put in a lot of effort into an answer only to never receive any reaction or feedback at all. It can feel like you are writing into a void, and that's not very motivating. I sympathize with the problem you've identified.

You do not directly lose reputation because you answered a question and the asker's account gets deleted. You only lose reputation in two cases: if the account that cast an upvote or an accept vote on your post gets deleted, or if your upvoted post gets deleted.
If the account that cast a vote is removed, the vote is removed. This helps limit vote inflation ...
The answer to your titular question is no, but you are not really asking this question.
Tl;dr: Your complaint is based on a strawman. I reject it.
You first complained about this here.
In that entire thread, I removed a total of two comments (besides some I wrote myself). Both because they were obsolete, one by other comments by the same user, the other (...
Given the current state if the system, I think the answer is "nothing can be done".
As long as there are any votes, you can not know if the asker voted.
There is no way to force them to vote or accept.
All you can do is not to answer questions of users that you know to be "ungrateful".
