well... if there was some way around the IP check when creating new accounts, if you could have something automagically create email accounts, then create blitz accounts using your referral ID, then perform the same basic steps necessary to complete the referral (sign up, create a player, spend skill points, done)
THEN you'd get a free 850 flex points each season, which wouldn't be a terrible thing, but you'd likely get flagged pretty quickly for it...
