Seems so. I have sent 7 RAD first and then 10 RAD afterwards but my coins never appeared. I had to use missing deposits to recover my 7 RAD and 10 RAD is still missing. I contacted support and reported, the owner posts lame replies, denies and said their "software is fine" and yet their github page reports "software is unproven and us it at your own risk", which is quite contradicting, even though when it's monitored and audited by the same owner, not only that he closed my ticket twice, he's totally being a dick.
