Not sure why the OP of the thread you have linked removed this topic but it's a topic I am very interested to follow. I do not believe any of the post to be incorrect as sportsbet.io did not deny any of it on their reply, it seemed very real. It's very possible that OP and sportsbet.io came to an agreement in private in exchange for removing the thread?
I am not sure, but I'd like to know more about it but I imagine we won't find out much more.
You shouldn't support a flag just because it "seemed very real". Anyone can create a thread on this forum and there's certainly no lack of that recently. Now you're part of the elite group of sockpuppets going around and supporting any flags they find against some entity they dislike, as well as known scammers (game-protect) and plagiarising ICO bumpers (hacker-whatshername). Well done.
The reason for supporting the flag was so that PlayerX could get the answers from sportsbet they wanted and for sportsbet to take the case seriously, that’s what they were asking for help to do. Had sportsbet supplies answers then I would have removed the flag. The flag helps them take it seriously. Nothing more.
