RE: Spamcop Blocks Facebook?

There's more to it than just that Facebook themselves occasionally fit
the profile of a spammer, and so some of the more stringent networks may
filter mail from them.

Facebook is a major source of drive-by malware, and some of the apps on
Facebook tread close to the spyware/adware/parasite line and so other
security tools/IP reputation services, depending on how they implement
the blocks for the droppers, and other undesirables, may actually filter
all traffic to/from the FB servers, as opposed to the dropper redirect
or app/adware host.

Regardless, for some subset of the world, reachability to various social
networking sites is becoming less reliable.

[ This discussion really should be on spam-l, not nanog. ]

I'm not affiliated with Spamcop, however, it's well-known among
those of us who work in this area that (a) Facebook has been spamming
for quite some time and (b) they're not the only "social network"
that's doing so.  So it's not especially surprising that one or
more DNSBLs/RHSBLs is/are listing them: they've earned it.

Point of order, however: Spamcop blocks nothing.  Mail system
administrators who choose to use their resources may block or
score or tag or ignore at their discretion.
