Well that explains a lot. As long as there are multiple points of communication handled by different people it is going to be interpreted as a good sign.
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.
An exchange as big as eXch can't be ran by one person and I don't think they have been infiltrated by law enforcement. Atleast we now have a response and things should go smoothly from here.
