No, it isn't. The SEC cannot revoke a registration that does not exist. To stop trading on non-reporters, they need to drag the company into court and gain a favorable ruling or persuade insiders to settle. This can take many years.
I doubt the SEC will impose a 10-day suspension on SLJB. IMO their primary reason for using this tool is to stop MMs from making a market in a security w/ warning the public being a far distant second. Since SLJB is an unsolicited pinkie, MMs shouldn't be making a market there. Also, Canadian regulators are already moving to stop trading.
