...just guide him by telling him that people who does that will be killed by god and police.....also show him some little punishment such as pick the pin

What do you mean by "pick the pin"?

internationalman:
for a 6 year old, I'd say that smartness..

Nurture that child well so that that smartness reflects in all the positive aspects of his life.

For a 6 year old to device a means as intelligent as that to extort you; I'd doubled his daily allowance if I were you......

What a genius

Scamming is wrong.

an apple does not fall far from the tree...... you plant okro U wan harvest cassava....Haba ....that's the street smartness U didn't let grow

U don't need to punished him, just do a proper parenting plan to guide him through this unwanted phase in his life.
