Dont take it seriously mate, I think he does not know what he is talking about

You do not force anyone to gamble and even if you are creating a hype to make people interested to join, it is also not something wrong and even if people lose while gambling, it is also not your responsibility. If we have to be responsible for people'e losses because our post about plan or strategy in gambling or maybe because we share our experience of nice win in gambling, basically he should also responsible for people's losses because he advertises gambling in his signature.
Nah, I'm not taking it seriously. We know each other very well, but I felt like he was blaming me just because I posted my plan. That didn't make much sense to me. I couldn't understand what I did wrong here. The gambler should be responsible for their own gambling habit. You explained it very well in your response already. It's not my responsibility if someone loses by gambling.
If someone blames others for their loss, they can even blame the forum because it allows gambling advertisements. They can blame the streamers because they encourage gamblers to gamble. You and I often share our experiences, and it can encourage people to gamble as well. But the gamblers themselves should be responsible for their actions.
