Merely stating that you admitted your guilt. Insiders (the term) can apply to any aspect of your choosing. Hedge fund managers, brokerages, MM's... you name it. It has many references my friend. Anyone who manipulates in an egregious fashion can be an "insider".
If you have illegally or legally shorted shares, let's say your group shorted 400,000,000 shares, wouldn't that make you an indider? Only those that know about the short would have that insider information. Or if you work for such a person that shorted shares, knew it, and bashed the stock based on that information, you would be a bashing on insider information.
