2018.8.23 update: 賣家已善意回應，全額退款；帳號只能後續等hilton如何處理
=========================================================================
以下分享慘痛經驗...
之前在板上跟上站次數好幾千的賣家，買了13萬點HH，結果幾天前突然帳號被鎖住不能
登入，打去問客服說帳號被close，在跟Fraud department來回N封信後(大約兩天一封)
終於有人願意主動告知，而不是罐頭信。
We received notification that the points transferred into your Hilton Honors
account were not authorized by the sender. As a result, the unauthorized
points were adjusted and future reservations were cancelled.
In order to reinstate your account, the original member you received points
from would need to contact us through the preferred email address on file and
confirm the transferred points were authorized.
Please note, without an authenticated email from the original member your
account will remain closed.
看起來只是被誤認為偷點數，需要sender寄信給他們才會解開，我那時心想還不簡單，
但是在對方寄信給hilton之後，還是帳號被鎖，繼續追問的結果(又過了3~5天)，結果是
賣家點數來源被系統認定有問題
Thank you for your email.
Upon further investigation, your friend's account was also closed for
fraudulent activity so any emails from your friend are invalid. The points
transferred to your account were stolen from other accounts. All accounts
involved in the transfer of stolen points are closed accordingly.
目前等待賣家回覆中，不知道版上有沒有其他受害者，希望大家以後買點要小心
我是覺得這真的很難預防，鈔票還有驗鈔技術，點數要怎麼分辨真偽@@ 有需要點數的人
可能還是透過官方渠道吧
ps. 另外有prepaid stay，因為封號hilton也把訂房紀錄取消，寫信問飯店GM，回說
As the reservation is a prepaid nonrefundable reservation I am afraid we
cannot refund the balance. The reservation is still in the system, would you
like me to cancel it or possibly move the dates to a more suitable date?
這下羅生門了，不知道大家有沒有相關經驗或建議?
謝謝!
