A third party always issues promos. In this case the company directed paid the third party and the third party runs the promotional campaign. Companies are usually are more discreet than this and have plausible deniability. And even then, they often get halted.
In this case, Liberty One Lithium doesn't have plausible deniability. They even admitted to directly paying Pyronix Media. "Since October 1, 2016, the Company has engaged Invictus Investor Relations Inc., First Marketing GmbH, and Pyronix Media Inc." The even admitted to already pocketing a half million bucks for themselves on this promo "Except for two directors exercising options to purchase an aggregate of 500,000 shares of common stock at $0.55 per share, and subsequent aggregate sales of 489,900 shares"
The only issue here is if someone from the OTC, SEC, or the British Columbia Securities Commission sees this and wants to take action.
On a scale of 1-10 for halt risk, this is a solid 10.
