As far as I know this is the first time this has happened, and I trust more the many houses that advertise here and when they have had accusations on the Scam Accusation board they have dealt with them than in this case they do not want to deal with them on the forum, even though the external platform is understood to be neutral.
It's also the first time I'm hearing this, but a casino which cares for its reputation will answer any questions and solve any issues doesn't matter where. If gamblers have this channel of contact (bitcointalk forum) as a reliable website to find reviews and support, so better that casinos come here to talk to gamblers on their questions and complaints. And even if a member of the forum gives a red trust to the casino, although they solved the problem, they shouldn't stop posting here for that reason, because it will look shady for other members who might come futurely with another accusations.
