do you feel bad promoting betting site like Vulcun?

No -- I'll explain why. I was one of the biggest anti-match fixing people ever as it killed my favorite game at the time, Brood War. First, fantasy sports is not the same as betting money on whether one team will win. Picking a roster with fixed pricing across multiple teams is actually impossible to match fix. Its not the same thing as betting thousands of dollars on one team to win or not. Second, I've played fantasy sports, often for money, for my entire life. Its a gigantic part of pro sports in the US. Fantasy football, March Madness brackets, fantasy basketball, I'd always get together with my friends and we'd draft and everyone would put $20 on that shit. It was really fun and never got out of hand. I like ESPORTS just as much and I see no problem doing the same thing with it. Third, the argument that adults have a responsibility to protect impressionable teens from vices is pretty stupid. Vulcun has a 18 year old age limit. Do you even remember being a kid? We all drank alcohol when our parents weren't home and played poker during high school lunch period for a few dollars. Beer is promoted every five minutes on TV. Do you really think that it's the NFL's responsibility to ignore a huge part of their audience that legally can enjoy an activity because there might be kids who see the ad and suddenly realize beer exists and then go crazy with alcohol poisoning? It's a ridiculous argument.
