Your friend accuses multiple users of being scammers with no evidence in every breath. That ain't a character assassination. That's a suicide.
You're a scammer, you confessed to it yourself:
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.
