It has happened several times now that a question is deleted by its author a few minutes after I post an answer.
I suspect it's because the question is a homework question and the user wants to remove evidence of receiving help online. I feel discouraged from answering more questions whenever this happens for several reasons:
- I lose access to my answer. Even after reaching 10K there is no way to find my deleted answers.
- I unintentionally helped someone cheat at homework. I already ignore homework questions for the most part because of this.
- No one else will benefit from my answer in the future.
Furthermore, this is more likely to happen when answering an old question, as it takes longer for someone to notice the answer and upvote it (which disables the author's ability to delete the question). So this discourages me from answering old questions.
Did anyone else notice this behavior? Can anything be done about it?
