Yes mad jock you are totally right. Their job is to target Arabs and other easterners as they don't know any better. Europeans are much more intelligent and spots fraud from far away or atleast leaves from a place they know is shoddy.
Therefore hero doesn't have much choice. They have to target the ones easier to trick.
But since the son of HCCA Athina Marini is at hero, the owner of hero has formed ties with HCCA and that's why still exists despite all the fraud they committing.
HCCA is the umbrella for hero.
