Haha, I've seen it happen a lot in the gambling industry, and it always makes me shake my head in disbelief. While I can't say for sure if these people are funded by competing sportsbooks and casinos, it wouldn't be the first time such dirty tactics have been used. But, in most cases like this, particularly within this forum, it's actually about inexperienced gamblers who either lack a true understanding of how online gambling works or held unrealistic expectations and ended up losing more than they could manage. So now they're looking for someone to blame. It's a common pattern – frustration and disappointment leading to finger-pointing.
