here are my copy edit suggestions. The reason why i substituted "your referral" for "the created account" is because that language sounds very cold and sterile. It needs to be geared towards people.

on the third section it's this:

"We will suggest to HIVE frontends that you, the referrer, will gain 3% beneficiary rewards from post earnings of the referred account. Please beware that referred accounts could always change this setting on a frontend, since it's a totally optional."

Consider changing it to this... (most noobs don't know the word "frontend" plus there were some grammar errors and awkward sentences.)

"We are recommending that Hive sites give you, the referrer, a 3% beneficiary reward from the post earnings of your referral. Please be advised that your referrals can always change this setting on a Hive site, since it's totally optional."
