There seems to be a plethora of idiots unable to either comprehend forum posting rules OR figure out what to do with a "use code tags" popup when they post code without code tags.

I had to bite my tongue when I saw a post from someone in a developing country asking for the complete code from people they are taking jobs from.

Unless you want to move away from a capitalist economic system, that is the situation you are stuck with. If I am willing to do your job for less money you are obsolete.

In that case, making a distinction based on where someone is located is (still) foolish -- you should not offer help or advise to anyone at all, because anyone could just as easily do the same thing. You will be worth more money if you can keep everything secret from everyone.
