Correct, but usually speakers and main invitees are listed on event itineraries and such. One showing up after registering and paying the fees is not labeled as invited by the organization.
Couple other scams try this announcement as if they are special invited companies.
One scam even made up their own rewards and trophy's and gave them to themselves at a show.
