Since all members and admins are users, I would use one table for user, members and admins adding one extra field "usertype".
Then I would add a table only for members, that would hold all extra fields that are member specific.
users {id, username, hashed_password, first_name, last_name, email, address, tel, user_type}
member_data {user_id, cleared_activities}
clubs {id, user_id, club_name, address, tel, available_activities}
If the extra member fields are just the one you mention, you could also keep it in the users table. For the users that are not of type member, this field will have NULL values.
users {id, username, hashed_password, first_name, last_name, email, address, tel, user_type, cleared_activities}
clubs {id, user_id, club_name, address, tel, available_activities}
