Wow...ok, let's take this how legalese might interpret it if you were being prosecuted (or contesting your account being shut off), and make a simple
Cartesian Product explanation of things that would cause contracted consumers to breach this.
Unsolicited: The receiver didn't as for it.
Defamatory: Defamatory material, even if it's about you.
Offensive: Good luck not finding a transmitted opinion that is not offensive to someone in the world, unless the scope is merely limited to the ruling body - stuff that pisses us off.
Abusive: This covers a wide variety of things, but is basically a step up from offensive, possibly expands scope.
Obscene: Despite the fact that there are generations alive today who grew up thinking anything Brittany Spears did in front of a camera was obscene, I imagine this scope is once again limited to the firm. They don't express their views on obscenity.
Pornographic: Don't keep porn here. For several reason, probably mostly image, but also for technical reasons like potential hot-linking to a stored file.
Menacing: Your kink, plans for world domination, or the informative chemistry video about the reactive applications of
alkali metals
Breach of Copyright: No one on
/. should need this explained.
Breach of Confidence: Ok, really? How can they enforce this? Only if your spurned friend, who knew you were on the mailing list for their leaked AND knew about this application of your contract would this be usable.
Breach of Privacy: PIs need not apply.
Breach of Any Other Rights: Conflicting breaches to be resolved in court, either way your service is toast.
--Times--
Store: Don't keep any material dealing with any of the above on our servers. (with no time limit, the first time something hits your inbox could trigger here on any of the above conditions)
Send: Don't forward, compose or otherwise cause any any material dealing with any of the above to be sent from your account.
Knowingly Receive: Getting into intent contracting here, but basically if they find that you've arranged for something that trips the material provisions above to your account, it's toast.
Upload: We don't care if something off the list above did come from your virus-infected computer, don't send it to our servers.
Download: This is the kicker here, and I'll expand after this table.
Distribute: Doesn't send already cover this definition because of its more restricted scope?
Download is the one that will fry everyone who's ever been the recipient of one of those bad forwards, like a goatse attachment. So let's say you get an email one day that is simply titled 'Check this out' with some explanation from a friend that this is funny and you have to see these pics. It's a horrible joke and it is a goatse-type attachment - offensive, obscene, possibly pornographic, and unsolicited - that you just: downloaded (you can't display it without receiving the information), and stored on your email account while you reeled. because each of those lists in the legal statement is effectively concatenated with 'or', you now have a breach of contract sitting in your inbox because you downloaded the horrible joke from their machines to yours.
It will also threaten anyone who's researching any controversy - You're supposed to see and consider points that may be very offensive to some. What trips the offensive clause, what doesn't, and will this be used as a new corporate censorship to the masses to cancel accounts on discovery of researching that corp's old skeletons in the closet? Deals like these are no deals at all, we need fresh blood in the provider industry.
So in addition to the fact that your ISP is handing over private details to non-law-enforcement, private companies to go trolling for copyright violations, they've also put your agreement (and patronage, I might add!) at risk by their own miopic contract design.
