So this SEC Investor Bulletin summarizes the rules

Quote:
The SEC may suspend trading in a stock when the Commission is of the opinion that a suspension is required to protect investors and the public interest. Circumstances that might lead the Commission to suspend trading include:
• A lack of current, accurate, or adequate information about the company, for example, when a company is not current in its filings of periodic reports;
• Questions about the accuracy of publicly available information, including in company press releases and reports, about the company’s current operational status, financial condition, or business transactions;
• Questions about trading in the stock, including trading by insiders, potential market manipulation, and the ability to clear and settle transactions in the stock.
So I don’t see anything that leads me to believe that the SEC would suspend trading based on not being current on filings and the company simply issuing a PR or two or three or "Official Notifications". Keeping shareholders informed of company status with PRs or 8-Ks is not going lead to suspension unless the SEC sees an effort to deceive with false information, paid promotions, or market manipulation.
To me a "PR Campaign" or "Official PR Campaign" that leads to suspension would have to be fairly extensive like in this example and not just a couple of PRs.
