On September 28, Shin (@hey_itsmyturn) said Milli Gold was at risk of disappearing and had failed to repay investors for several days:

Milli gold, which I warned about over a month ago is about to be gone for good, they are not paying the investors back for days and days.

The post linked to Shin’s August 26 warning, which cited an unnamed insider:

Dear Iranians,
This is Milli[.]gold "gold trading" platform.

An insider tells me that Milli is short roughly 300 kilograms of gold. The gold is "sold" but did not hold.

If you have money or gold there, get it off the platform, IMMEDIATELY.

If you don’t want your assets gone

Shin also reposted that earlier warning on September 28 with the comment:

I warned you, didn't I?
