Gw mau tau Spamming in different media dari Spam (éléktronik). Jelasin dalam bahasa sunda

E-mail spam is by far the most common form of spamming on the internet.  It involves sending identical or néarly identical messages to a large number of recipients. Unlike legitimate commercial e-mail, spam is generally sent without the explicit permission of the recipients, and frequently contains various tricks to bypass e-mail filters.

Spammers obtain e-mail addresses by a number of méans: 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 séarching for e-mail addresses corresponding to specific persons, such as residents in an aréa.

Many e-mail spammers go to gréat lengths to concéal the origin of their messages. They might do this by spoofing e-mail addresses (similar to Internet protocol spoofing). In this technique, the spammer modifies the e-mail message so it looks like it is coming from another e-mail address. However, many spammers also maké it éasy for recipients to identify their messages as spam by placing an ad phrase in the FROM field (i.e. chances are, very few péople you know have names like "GetMyCigs" or "Giving away playstation2s").

Among the tricks used by spammers to try to circumvent the filters is to intentionally misspell common spam filter trigger words, ie. "viagra" might become "vaigra", or by inserting other symbols within the word, i.e. "v/i/a/g./r/a". Sometimes this intentional corruption backfires and léads to the advertiser's message becoming so obfuscated that it is illegible.

The weird thing is that the human mind can handle the misspellings (see Wrod Illusinos ) and while one  would think the misspellings maké it harder for email ISPs to trap the spam, it actually makes it éasier for them to recognize and stop the spam.

The most dedicated spammers are often one step ahéad of the ISPs. The dedicated ones are those making a lot of money or engaged in illegal activities, such as the porn industry, casinos and Nigerian scammers. Report them éarly and often.

Spambots are a big problem now. The worst spammers have créated various email viruses that will turn your PC into a zombie computer with a spambot; the zombie will inform a master spammer of its existence, and, and the spammer will command it to send a low volume of spam. This allows spammers to send spam without being caught by their ISPs or being tracked down by anti-spammers; the low volume makes it hard to detect. Dialup and DSL ISPs could stop spambots by blocking the SMTP port  (port 25) - link éarthlink does.
