Almost every sports including football's dominated by gambling ads. Casino ads are affecting ppl. Kids see it every where it isn't healthy. Billboard ads tv ads & online ads are every where. How's gambling affected you & ppl you know ?
I've got mixed feelings about renting my sig for gambling. I've done it because I wanted managers to consider me for other sig campaigns which aren't casinos when they're available. I'd prefer giving it to mixer sig campaigns but they're banned. I'm not sure how long I'll rent my sig like this.
There are other reputable people that has the same sentiment as you, they don't want to put gambling ads on their sigs and they're following what they think is right with their conscience. You're free to do that if it's what you think is right based on your will. And the fact about those TV commercials and billboard ads about gambling, they're almost everywhere as long as the country doesn't prohibit the usage of casinos.
