How to Stop Spam
The good technology that is currently available to stop junk e-mail isspam filtering software . The simple-minded filters use keywords such as " sex , " , " xxx , " " viagra , " etc . , in the capable job to attempt to key out and delete junk e-mail . These unproblematic filters are easy to parry by spelling " sex " as " s - e - x. " There are , of course , chiliad of shipway to spell out " sexual activity " if you are willing to add extra characters like that , and it is hard for the dim-witted filters to keep up . Also , simple filters are most likely to deflect " real " e - ring mail that you do want to receive . For example , if your friend sends you her favorite formula for baked chicken breasts , the filter blocks the e - mail because of the word " titty . "
More forward-looking filters , sleep with asheuristicfilters andBayesianfilters , strain to take this simple-minded coming quite a morsel further to statistically identify junk e-mail based on word patterns or word frequency . But there are still ways to get around them ( mainly by using short subject matter ) .
The word " puklq " is random , and it is different on every e - post the spammer sends .
There are several organization that issue lists ofIP addressesthat are used by spammers . Any expectant spammer will have an array of host machines smash out junk e-mail messages , and each host machine has its own informatics address . Once spam is detected from an IP address , that IP speech is put in a list ( Spamhaus.orgis one of many organizations that assert such lists ) . Companies that host due east - mail accounts can attend at the sending IP address of every e - post and filtrate out those that appear in the Spamhaus.org tilt .
Spammers get around this approaching in two unlike ways . First , they change their IP address often . The inauspicious job with this approach is that the former IP address that spammer discard get recycled , and the hoi polloi who get these discarded IP address find them to be useless – they are defile by their former connexion with junk e-mail , and can not be used for beam logical e - mail .
Lately , spammers have started to get more belligerent . For deterrent example , it is call up that recentviruseslikeSoBig . Fwere sent out specifically to recruit " zombie machine " for spammers . Thezombie machinesare generallypersonal computersowned by unsuspecting private citizens who materialize to condense the SoBig computer virus . The computer virus opens their auto up to spammer , who can then route spam e - mails through their machines . Since the IP addresses of these machine are new , they do not come along in the IP reference blacklist and millions of junk e-mail e - chain armour can route through them before they get blacklisted . The zombi machines have also been uses for denial of overhaul attack on places like Spamhaus.org .
Another front in the war against spam is lawmaking . For exercise , it has been suggested that the U.S. federal government set up a national " do not spam " listing identical to the nationalDo Not Calllist contrive to obstruct telemarketers . However , it is believe by most mass that spammers are so obnoxious that they would set up spam waiter in foreign country and actually use the " do not spam " leaning as a source of saucy e - mail addresses .
Another resolution would be an " opt - in " list . Under this proposal , only those masses who specifically request junk e-mail tocopherol - chain mail would get it . However , the United States congress seems to be heading in the opposite direction . As noted onSpamhaus.org :
The last front in the war on spam is the elimination of e - mail in the traditional horse sense . Many business are being forced to take this approach . Even the White House has been squeeze to follow this way . Today , if you want to send e - ring armor to the president of the United States , you do it by fill out an online shape . Even HowStuffWorks has been forced to use forms . It used to be that you could charge e - mail directly to private HowStuffWorks stave and departments , but those e - post savoir-faire start to receive so much junk e-mail that we now use a stage set of on-line forms , instead .
That may be what happens to all e - mail in the long run . The amount of spam , and the inability to control that spam , may become so difficult that the traditional atomic number 99 - mail system we make love today collapses and gets replace either with forms or with a exercise set of advanced , secure servers that put spammer out of business enterprise .
