how susceptible are we to spam? with most of us displaying our online code, it's rather easy for somebody to collect our wii email addresses and start spamming, no?
Unlike email, friend code systems allow for explicit filtering. With the (lame) Wii code system we have in place right now, you need both sender and receiver to accept each other, so unless you're a retard and keep the spammer in your address book, it shouldn't be an issue.
