May need to read more for your jurisdiction (depends on your case law in your country). Usually it's explicit communication between the parties to price fix. If you were using those services that share salary information to communicate to your competitors, it probably does. If your employees/ex-employees do it without you telling them to (with evidence that you did), probably not.
