Should we consider requests that ask for aid in reverse engineering / transcribing compositions valid?
By this I obviously mean well constructed questions that the OP has put clear effort into, articulating where they're at and what they need help with, not straight-out requests to provide the poster with a complete works. But, badly constructed questions aside, should they be tolerated at all?
If yes, then what legal implications might we need to think through?
In some cases allowing this might not fall foul of any law or copyright, but I think we would need to look into what can be done to protect ourselves from anything of the like happening, since, inevitably, other cases won't be so 'free' - what do sites that host music sheets / chords / tabs en masse do? Is there somewhat of an umbrella policy we can get under?
