Suppressing comments which reveal the answer

Question

Many users are typing the literal answer of a question in courses, in the comments of that question, without any other texts and thoughts. That is:
1) annoying, it feels like cheating;
2) useless, even if you want to cheat. You can't access the comments before answering;
3) not-educating, since SoloLearn is to learn from it and from each other.
Is it possible to mark these comments, so that they can be removed by admin-users?
edit: I mean questions/exercises in the courses, not in the Q&A

Answer 1

I believe there is the option to report comments in the tutorial slides. That said, I don't think they pose any harm or downsides to the community.
As you have said, people can't access it before answering, so the comments which reveal the correct answers with explanations are meant to clarify and teach those who didn't get the question, instead of being some form of cheating. Your third point correlates with this as well.

Answer 2

Suppose you know a really good answer to a really good question that people can take advantage of. I dont see a problem doing that but I remark that both q & a should be good to do it.
