This rule could also lead to having to sell to Gators or other rivals. I persoanlly have tickets I have bought on the Boosters ticket exchange board, that I paid more than face for and need to sell, but cannot do it here where I feel I could know with some degree of certanty who I am selling them to.
Like someone else mentioned, the fact that they let you sell them at all on here, would subject them to some degree of liability if that were the law.
I am on here almost every day and would like to be able to sell the extra tickets I have to fellow Noles, but am not allowed to. Just another angle to think about.
