I've already opened this thread: https://bitcointalk.org/index.php?topic=5290588.0

But now I don't know how to move it to the proper section here: https://bitcointalk.org/index.php?board=83.0

If you can move this thread to Scam Accusations or ask a moderator, please kindly do so. Or please just tell me who can I message from moderators team to move this thread. Thanks.
