If I see a series of questions that are clearly homework (from my class!!!), should I tag them as such?
If so, what should I say in the summary so it doesn't get rejected?
I have seen several comments like J.M.'s here on meta.MSE saying that the homework tag should only be added by the OP, or after the OP has said that it is homework. A possible reason is that false positives could be seen as insulting. But I still see people adding the homework tag to others' questions without the OP having said that it is homework, and there doesn't seem to be a consensus.
I'm very interested in other people's views on this.
Here are a couple of related discussions from meta.SO:
