IMO, especially given the unnecessary capitalisation of many other terms in the text, occasional unnatural punctuation and spelling errors, what is meant is plain old spam a.k.a. junk mail

Spam, bulk email
Spam originally meant to post many off-topic and inappropriate postings (mostly commercials) to a newsgroup(s), making it hard to read by lowering the signal to noise ratio. The term spam, of course, is the product manufactured by Hormel, Inc. It came to it's current meaning because of a skit by Monty Python's Flying Circus in which a group of Vikings begins singing "Spam, spam, spam, spam.." and drowning out anyone else who was trying to talk in the area.
Spam has also come to mean unsolicited commercial email (UCE) which is also known as bulk email. Spam has a much nicer ring to it, as well as being able to create nice words such as "spammer" and "spambot."

Side note: The name "spam" is actually a trademark of Hormel, Inc. but they seem to not mind others using it, as long as you keep it lowercase. See http://www.spam.com/ci/ci_in.htm for Hormel's official statement on the matter.

P.S. Spam is short for "spiced ham." :)

Electronic junk mail or junk newsgroup postings. Some people define spam even more generally as any unsolicited e-mail. However, if a long-lost brother finds your e-mail address and sends you a message, this could hardly be called spam, even though it's unsolicited. Real spam is generally e-mail advertising for some product sent to a mailing list or newsgroup.
In addition to wasting people's time with unwanted e-mail, spam also eats up a lot of network bandwidth. Consequently, there are many organizations, as well as individuals, who have taken it upon themselves to fight spam with a variety of techniques. But because the Internet is public, there is really little that can be done to prevent spam, just as it is impossible to prevent junk mail. However, some online services have instituted policies to prevent spammers from spamming their subscribers.

There is some debate about the source of the term, but the generally accepted version is that it comes from the Monty Python song, "Spam spam spam spam, spam spam spam spam, lovely spam, wonderful spam…" Like the song, spam is an endless repetition of worthless text. Another school of thought maintains that it comes from the computer group lab at the University of Southern California who gave it the name because it has many of the same characteristics as the lunchmeat Spam:

Nobody wants it or ever asks for it.
No one ever eats it; it is the first item to be pushed to the side when eating the entree.
Sometimes it is actually tasty, like 1% of junk mail that is really useful to some people.

I expect that OSS is Operational (or Operations) Support Systems and SPAM Service Provisioning and Account Management. These fit the context of the other items in the list.
