How to make +reputation give points to the receiver rather than the giver?

Back with uCash & uShop, this was the only way I'd handle points - through reputation. Points through reputation was the hardest to exploit because it required two people, which made it easy to catch them for cheating.

vbplaza looked great until I found out that reputation was given to the GIVER rather than the receiver! That just doesn't make sense to me. Is there an easy way to fix it?
