Forum:Does the Game know?

Alrighty, I know after much whining and complaining, I have finally killed Crawmerax legally and legitamately numerous times. I have started to delve into the modded weapon world (privately only, otherwise, my 2210 purple rarity shield and legal weapons are used) when fighting Craw to make it easier and go faster. I have no pearls to date. When I fight him, i have the modded RoseOmega and an orange rarity serpens knock off titled "shredder shredder". My question is, does the game know when I'm using modded weapons solo and gives me worse loot or not? and please don't attack me for privately using modded weapons. IbanezRokr.
