You sometimes meet OPs asking a question that you are eager to answer by providing the sufficient hints, possibly in a condensed way or by linking to published solutions, but in a way that is deemed to unlock the enquirer.
Some of them will start moaning that they do not understand, would like more support, are lacking skills, that it is too hard... and in the end you understand that they actually want you to craft the complete solution for them.
In other cases, you see that the OP is indeed not skilled enough and the "fastest" way out is to do it all for them rather than wasting time to explain.
How are these situations handled on Mathematics ?
