15. If my acts (e.g. distributing a copyrighted work without permission) are not done for commercial purposes, will I be immune from criminal prosecution for copyright infringement?

No. If you distribute a copyright work for non-commercial purposes but the distribution is to such an extent as to affect prejudicially the copyright owner (e.g. loss of income or business opportunities), you will also incur criminal liability (see section 118(1)(f) of the Copyright Ordinance ).
