Maybe I'm wrong on this, and I'm not a mailadmin anywhere nor have I been or pretended to have been in the past. But I'm pretty sure FB only sends you mail based on the prefrences you choose, and I know this is the answer you where given so mostly a statement. How does that equal spam 
Hmm this just me of this post, where supposedly Facebook will be making the move into Webmail for its users. Interesting. Coincidence or not!?!?

Invitations. Kind of Bulk. Never asked. Unwanted. Coming again and again. Boring. Spam. They keep storing email addresses without their consent. Not even mentioning project Titan.
If FB users sends emails to themselves, that's their problem indeed. If they complain about these emails, that's FB problem to have dumb users.
If recipients with nothing to do with FB receive unwanted emails, that's FB problem to find a way to stop that.

The default is for everything 'on'. They will send to any email address
with notifications and mail regardless of signup and they don't honor
bounces in any 'email address doesn't work so don't mail it' lists they
might or might not employ.

Facebook, like many similar sites, rather aggressively requests that its
users supply their email credentials so that the site can "invite" their
contacts. All of them. Every stinkin' email address they can mine.
If the user/victim falls for this, the social networking site will
scrape every email address it can find in the user/victim's contact list
and "invite" them to join. These invitations are often forged to appear
as if sent from from the user/victim's email address.
Similarly, if anyone on Facebook uses the site to forward content (often
Trojanned), then Facebook now has the address of the forwardee and will
"invite" and then 'remind" repeatedly.
So it isn't the Facebook members that Facebook spams (although they
might do that too). It's the non-member addresses they scrape from
their members.
As it's entire contact lists that get scraped, it's bulk. As the people
being "invited" and "reminded" didn't ask for it, it's unsolicited. And
it's obviously email. Put those together and you get Unsolicited Bulk
Email, AKA spam. And those sites that send with their user's name as
the sender are even more egregious because they are forging header
information.
Social networking site users are not the site's customers. They are the
site's product. This product is sold to advertisers and data-miners.
If I leave all boxes checked to send mail/notices/app requests to
everyone in my list, or if I give FB my gmail password to pull all my
contacts and send them an invite, its pure @ my request, sure FB is
happy I do it, but it is no way spam. Its like calling 5 ICMP packets
a DDoS.

This is dead wrong. You're not authorized to solicit bulk email on behalf
of third parties: only they are. In the absence of solicitation from
the *recipients*, bulk email is spam -- by definition.

I'm not going to both on this thread anymore.. waste of time. Sorry
for the bulk mail/spam generated by my replies to nanog.
I'll stop feeding the trolls now.

So if all 100 million zombied machines sent you 5 ICMP packets each, you
wouldn't feel DDoSed at all?
Yeah. Thought so.
Almost all spam is OK with the sender.
It is the recipient of unsolicited bulk email that tend to be offended.
As are the recipients of unsolicited commercial email.
I tend to get terminally annoyed at unsolicited email and let [word for
All-Mighty} sort them out.
Nice recovery attempt for a lost cause.
Also, Facebook sends mail from many different IP ranges, and non-Facebook
(but @facebook.com) spam mail manages to get sent from overlapping IP
ranges on occasion.
Facebook tends to send mail from address+id@facebook.com, where 'address'
is something like 'notifications' and 'id' is some random string. Some
spam mail packages cannot distinguish this from address@facebook.com,
which many of the spammers who try to spoof Facebook use (using the same
common 'address'es as Facebook does). If you don't watch what you are
doing, this can result in significant amounts of false-positives on manual
sender-based blacklists.

Okay .. here's a fun exercise (granted, as a .edu, the FB stats are
statistically over-represented) .. this is yesterday.
total email : 1,594,435
from @*facebook* : 17,274 (1.1%)
Taken as a total of *legitimate* email that got through the spam filter ..
"legit" email : 79,072
from @*facebook* : 16,383 (20.7%)
Facebook's "notifications" account for ~21% of the mail making it past
the border SPAM appliances.
