Good information may bring him into jail and regret for the rest of his life.
I think that is an important point. We have a moral responsibility to advise people if what they are proposing is illegal or will get them into trouble at work/school/college.

The problem is that people come here with very little knowledge and experience, have heard of and half understood a concept, and think this will allow them to achieve something. The classic example is the student who wants to bypass his institution's policies and firewall to use P2P and play internet games . I do not think that it is worthy of this site to simply flame or neg such people, if we are a true security minded site we must tell them that what they are proposing is a bad idea and WHY it is.

I am sure that many of us encounter this in the workplace............the user says: "can you get this to do X,y and z" when what the SHOULD be asking is "I want to do a, b and c; how can I do it"..........I am afraid that I have a zero tolerance of half baked user "solutions"

I think that Lansing_Banda's post was reasonably balanced.............it explained the principles/concepts but not HOW to do it.

we COULD give out information knowing its for illegal purposes
In which case we would be:

1. Aiding and abetting
2. Inciting
3. An accessory after the fact
4. Conspiring

And probably a whole load of other things as well

just my thoughts on the matter
