As an independent user, I must say that I think you have a horrible take.
This isn't blackmail. Personally I think he should just open the flag, but that's his decision and if he wants to give them some time to consider paying him first, there's nothing wrong with that. It's not like he's making shit up and threatening them privately. And the compromise already happened. He agreed to let a third party review the situation and agreed to honor the decision.
The decision was made in his favor. Now the Coinplay is ghosting him.
Also, there's nothing wrong with signing up for however many sportsbooks/casinos you want. I've likely signed up for closer to 100 gambling sites over the past 15 years, maybe more, always looking to find the best options out there. This is a ridiculous reason to not trust someone.
I appreciate your perspective on the matter. However, I still believe that using threats to resolve the issue can be counterproductive.
As for signing up for multiple sportsbooks, I agree that exploring different options is normal for most users. However, it's essential to respect each platform's terms and conditions to maintain a fair and trustworthy gambling environment for all.
Interestingly, you mentioned promoting Sportsbet.io, which has had its share of similar scam accusations in reviews. It's crucial to consider all aspects of a situation before taking a firm stance, as each platform and user experience may differ.
