[feature] Require email for refferal reward

[DWAA1660]

🚀 Feature Request

Is your proposal related to a problem?

Provide a clear and concise description of what the problem is. For example, "I can't change x and it makes me have to do manual work"

I cannot easily verify emails are real users or just random characters people fill in when they get reward

Describe the solution you'd like

Provide a clear and concise description of what you want to happen. For Example, "Automate the changing of x so I don't have to do it manually"

Maybe have it so if require email verification is set to true users don't get referral reward until user verifies there email address so at-least its more difficult to bypass.

Additional context

Is there anything else you can add about the proposal? You might want to link to related issues here, if you haven't already.

Maybe also add so you can tell what users a user referred when looking at them so its easier to stop abuse of it.
