Yes. The more Fan Tokens you own, the more influence you can exert because every Fan Token gives you one right to vote. For example, if you own ten Fan Tokens, your vote will count ten times in any poll.
However, each team will impose an upper limit on how many voting rights one individual supporter can have, irrespective of how many Fan Tokens they own, for integrity purposes and to ensure that no one fan can control decision-making. This will vary from team to team.
