People that volunteer for the East Coast Comic Expo or any other organization that exists to make a profit for an individual (or a group) are obviously being exploited.
Volunteering for such an organization would be like donating time to McDonalds or any other corporation.
When these types of groups tell people online “It’s your event! Give us your ideas!” they are once again attempting to exploit naïve individuals to help the organizers make money.
It’s common sense.
My advice: Don’t get fooled. Invest your time into activities that benefit you and not the bank accounts of others.
