It's possible that there's some trouble with exch.cx, as their forum representant hasn't written anything on the
official ANN thread for several weeks (even if some forum members have asked questions). There was however a fee change (for BTC/XMR) on their interface in the last days, so someone seems to be managing the site. (Don't know about the support chat, didn't have contact in the last weeks.)
It would be sad if this service didn't turn out to be what several of us (including me) thought. Even if I wouldn't have a problem to advertise exch.cx for free for a week or two, I will proactively delete the signature so in the case there is an issue (legal problems, for example.) nobody is directed there, and also comment on some recommendations I made for this service in the last weeks. This is of course only a preventive measure, if exch.cx is coming back to the forum and regularizes the situation, then I'll be happy to recommend them again.
Thank you for excellent campaign management, icopress
(PS: It turned out it normalized fast.
