I agree to you that they're making it look like there's a maintenance but that's the escape goat that they did. It's so long until this thread has been made and there's no single reply from them.
As others stated here, when you just type goosebet.io it will just lead you into an error website. But when you include the https it will redirect you to the site. It's alarming as they remain the site open luring new users that are not aware of the site's current situation.
Yeah, I just checked it.
It's very questionable what they've been doing.
The Live Bet board is still active and currently, there's a few active player playing dice (about 2 users).
But that was 1-2 users only that's playing right now so I will take this as good news that others are now aware of the site's status. Or maybe this is also a user from the site itself to show visitors that their site is still running.
Who knows.
It's possible that those two active users are from the owners side and they're testing it. I hope that it's not another user that's not part of the team to avoid the same problem that op dealt with.
