So it's accurate to suppose gamblers feel offended by such campaigns.
Anti-gambling campaign I guess works only on gambling platforms and casinos that has no business permit that's consider as illegal, and mostly people are addicted to those illegal gambling because they can't afford to play in a casino, so in short, gambling addiction is really hard to prevent since people will always find a way to gamble secretly.
Besides, it's their choices to play gambling, however, their logic seems not working because after they lost their money in gambling, they will ask help to their local Government for food, how ironic.
