No, both of you are just proving to me that you can't read.
Zoro in the past was a pirate hunter and became known for being a pirate hunter. If he stopped being a pirate hunter, nobody cares, but that was the main reason he is known to this day...
Another example of why both of you are too stupid:
Messi became known for being the best football player in the world, Messi today is no longer a football player but a medic, but the main reason Messi is known is not because he's a medic but for having been the best football player in the world.
Zoro was a pirate hunter = Yes, he was.
Zoro is known for being a pirate or a pirate hunter = A pirate hunter.
