	Secure Computing - How Spammers Fool Spam Filters - And How To Stop Them
		Blacklist administrators are forced to constantly revise lists, and the lag-time between when a spammer begins using a given server and when the fllist administrator is able to identify the new spam source and add it to the fllist allows spammers to send hundreds of millions of e-mails.
		Spammers consider this constant state of flux a part of doing business and are constantly looking for new servers to send spam messages.
		Spammers would not spend the time required to go through a large number of challenge-response e-mails, so they drop the address and move on to those users who don’t use such a system.

		Spammers obtain e-mail addresses by a number of means: harvesting addresses from Usenet postings, DNS listings, or Web pages; guessing common names at known domains (known as a dictionary attack); and "e-pending" or searching for e-mail addresses corresponding to specific persons, such as residents in an area.
		Spammers send their spam largely indiscriminately, so pornographic ads may show up in a work place e-mail inbox -- or a child's, the latter of which is illegal in many jurisdictions.
		In 2004, the seized Porsche of an indicted spammer was advertised on the internet, which revealed the extent of the financial rewards available to those who are willing to waste everybody's time and was a popular item because the car had been confiscated, which was seen as tough justice, but also sweet vengeance.

		Spammers have developed a variety of spamming techniques, which vary by media: e-mail spam, instant messaging spam, Usenet newsgroup spam, Web search engines spam, weblogs spam, and mobile phone messaging spam.
		The worst spammers create email viruses that will render an unprotected PC a "zombie computer"; the zombie will inform a central unit of its existence, and the central unit will command the "zombie" to send a low volume of spam.

	E-mail spam - Wikipedia, the free encyclopedia
		Spammers frequently seek out and make use of vulnerable third-party systems such as open mail relays and open proxy servers.
		Spammers have also subscribed to discussion mailing lists for the purpose of gathering the addresses of posters.
		By doing this, spammers protect themselves in several ways: they hide their tracks, get others' systems to do most of the work of delivering messages, and direct the efforts of investigators towards the other systems rather than the spammers themselves.

	Six Apart Guide to Combatting Comment Spam
		Or, to defend against spammers who send a flood of spam -- dozens or hundreds of comments in the span of a few minutes -- your comment script could place a limit on the number of comments that can be sent from a single IP address during any given period of time.
		Spammers often target old entries because the spam is less likely to be noticed by you than on your most recent entries.
		The less a spammer can rely on a particular configuration, the more work they must do and the less attractive the weblog medium is as a delivery vehicle for their payloads.

	Fighting Spammers With Honeypots: Part 1
		During automatic harvesting of valid email addresses on the Web, spammers may sometimes be recognized because of the tools they use by checking the User-Agent field sent by their browser [ref 6].
		If the spammer connects to the proxy and asks to go to a Sendmail server while you are faking a Qmail server, he may notice that it is a honeypot.
		If the spammer targets an SMTP server he owns, for example for his first email, he will notice that the SMTP session he sees though the proxy is not the same as the one going to his mail server.

	FAQ: How do spammers get people's email addresses ?
		There have been reports of spammers demunging email addresses on occasions, ranging from demunging a single address for purposes of revenge spamming to automatic methods that try to unmunge email addresses that were munged in some common ways, e.g.
		Spammers regularily attempt to get the lists of subscribers to mailing lists [some mail servers will give those upon request], knowing that the email addresses are unmunged and that only a few of the addresses are invalid.
		Spammers use this information to get extensive users list from hosts, and of active accounts - ones which are 'live' and will read their mail soon enough to be really attractive spam targets.

		Linford claimed that the law that is meant to deter spammers is full of loopholes and its sanctions are derisory, effectively giving UK spammers the green light both to increase their activities here and form partnerships with overseas spammers.
		While Italy can impose fines of up to €90,000 and prison sentences of up to three years under the e-privacy law, spammers in the UK face fines of just £5,000 in a magistrates' court (or an unlimited penalty from a jury) and no risk of jail.

	Porn gets spammers past Hotmail, Yahoo barriers \| CNET News.com
		Because the disguised word is virtually impossible for a computer to read, spammers need a human to intervene, which ruins their automation process.

		In the background, spammers have already used scripts to automate the Web mail accounts opening process to the point where they need a human to "read" the Captcha graphics.

		And as everyone struggles to sift spam from their inboxes, valid messages are sometimes overlooked or deleted, which makes e-mail less useful and reliable as a channel for communication and legitimate e-commerce.
		For example, we are battling spammers who set up numerous e-mail accounts and move from service to service to avoid detection.
		Spammers also go to great lengths to conceal or "spoof" their identities, so we are partnering with other service providers to identify and restrict mail that conceals its source.

		Often it's because spammers keep coming up with new tricks to work their way around anti-spam technology, forcing the good guys to continually play catch-up.

		Spammers have been successful enough that the opposition has tried adopting some of their tactics.

		Spammers are exploiting a little known vulnerability in Microsoft's Hotmail service to send more junk mail automatically.

		Although Rosenthal concedes that the small amount of spam coming through with a Dav message header suggests that only a few spammers have exploited the vulnerability, he believes that it is only a matter of time before others catch on.
