Not necessarily so. It may be the case in your fraternity, but others may have different rules regarding election to membership. A person may be blackballed for pledgeship one semester may wind up being selected in another semester, so long as they meet the membership requirements of the fraternity or sorority (no current or prior initiated membership, currently enrolled at the college or university, etc.).
