28% USA
5% South Korea, 5% China, 5% Russia
80% of US spam is generated by a group of 200 hardcore professional spam gangs

How is spam sent out? 

Most ISPs do not allow spam. So spammers conceal the origins of their
spam by sending it through insecure servers belonging to unwilling third
parties. These "zombie networks" of infected PCs span the globe.

How do spammers get my e-mail address? 

* E-mail addresses posted on Web sites in plain HTML (unobscured)
attract the most spam as they are harvested by spambots
* Basic e-mail addresses (short names, initials like bob@ or tse@, basic combinations like larryt@ receive more spam
* "brute force" or "dictionary attacks" (e-mail is sent to common surnames and first initials)

Fighting Spam 

Best solution: an "Antispam Cocktail" (a mix of strategies)

* Remove or obscure address from public websites
* Use multiple e-mail addresses; create a free email account (aka disposable e-mail address) for use when registering with websites (recommendation: gmail)
* DNS-based blackhole lists (lists of IP addresses of known spammers, open relays, zombie spammers etc)
* Don't respond to spam from unknown companies
* Don't buy from a company that spams. Don't visit their website, don't ask for more information
* Disable HTML in email software
* Switch from Outlook to another email software
* Set up multiple levels of spam filtration
* Contact your ISP and ask for help setting up a spam filter
* Use spam filtering in your email client (* Spam filters detect spam based on the content of the e-mail)
