If it is a one-man business
Doubt it.
eXch (OP) uses perfect English, while the exch.cx website and the support messages use slightly broken English.
When someone so reputable is gone for a month, I'm not worried about their integrity. I'm worried about their physical wellbeingness.
I hope the people behind eXch are very careful with their anonymity.
They've been out for a month, then back with no explanation. The site doesn't have a canary. I don't recall if it had one.
Wouldn't be surprised if exch.cx was infiltrated by LE and all transfers are under scrutiny now.
This Animesh phishing is a convenient red herring.
