Is there a chance some really big shit is going on in their lives, and they are incapable of going online? For like... A month? I really can't believe this is an exit scam. The service seemed legitimate.
I'm really pissed off, and not because I lost money; fortunately, I had grasped that "don't leave coins to third parties" cliché. I'm so pissed off because I've been advertising and recommending this shit for months, in such a way that I'm practically part of this scam. And it's just feels awful.
It makes you question the integrity of the service you're currently carrying in your signature.
The thing that sucks is we can't even know for sure if a service is going to end up being a scam. We liked ChipMixer due to their reputation and long-running service but who would've know if they end up wanting to scam anyway.
