At the end of last week, I answered a question which seemed like homework. I didn't just give the answer, only some suggestions on fixing the implementation. It seems that after I helped the user, he went back to edit his question and removed all of the code. I rolled it back, but then he went and edited it out again. Suspicious, I looked through his ask history, and he does it to almost every question he has asked. Some of them do contain the code, because other users have rolled it back.
I was hoping that the user would accept my answer, hence why I checked back today. If he keeps removing code, should it just keep being rolled back? How should a situation like this be handled? I suspect that the user is doing so to avoid being found out by a teacher/professor.
