It's about social media but sharing it on a forum is a different thing.
That's why someone who's sharing it on a forum doesn't have to worry even there are bad people out there who have read your experience and story.
They can't do anything with it because they don't know you personally and that's what I'm telling and as for sharing it on social media, I guess that not that many of these folks do that. They don't want people to know that they're actually a gambler.
Maybe they can feel safe to share their success story on a forum since they do not share their identity and can tell about their winning here. But we do not know for sure because the bad guy will try many ways to scam those winners and get their money.
Some people feel not right if they share their winning stories about gambling on social media because, in some countries, gambling is a bad thing or not recommended way to earn money. So maybe that will be up to us how we will share our win story about gambling or other things. Hopefully, we can know where is the right place to share those stories so it will not attract bad guys.
