Wow, thats kinda fucked up. I don't really know who it could be but I don't think they would succeed. Even if they did, they wouldn't go unnoticed for too long. The message suggests that someone has control or influence over at least 3-5 accounts on DT, but there's also a chance theyre just bullshitting you.
I never really follow up what happens to flags I supported or opposed. Probably should.
I also think they are just trying to get some money from the casino and have no idea about the Bitcointalk forum. I just figured out that a user
gh0573d opposed the flag while there were three DT supporters. What makes this user oppose the flag? I would love to hear it from this user. Could it be this user who sent the offer to this casino?
I think I have seen a casino that falls for this kind of trap. Their account has dozens of positive feedback from newbie accounts that didn't even show up by default for an obvious reason. I think this is the same group which send such offer to the casinos.
