We do allow people to post their referral codes/links of some rewards programs on our website. Normally, you will see a note like this: "If anyone wants to leave his/her referral code below, please use the following format ONLY...". Please follow the instruction to provide your referral code/link. And, repeated entries of referral code/link will be deleted (including the original one and the repeated one). We will check on this regularly. Thanks.
