What this section does is:

• Manually update our database to pretend that the user has RECEIVED OUR EMAIL and CLICKED THE VALIDATION LINK.
• It will only do it if we think the email address is actually valid.
• Meaning: it won't do it if the email address is "travis".
• And it won't do it if the email address is "john@travislaborde.com" even though that LOOKS good because there is no such actual email address at the travislaborde.com domain.
