Ask Are referral codes case-sensitive?

[GameOver]

Referral programs often use unique codes or links to track new members who sign up through existing users. Some systems treat uppercase and lowercase letters as different characters, while others do not. Since the BMF.io Publisher Program offers rewards for every new member who registers and becomes active using a referral code, it is important to know how the system reads these codes. If a user types the code with a different letter case, will it still count as a valid referral? Are all referral codes on BMF.io case-sensitive, or can they be entered in any format without affecting the reward? Knowing this could help avoid mistakes during registration.
