* An alternative approach is to leave your real address on message groups but disguise it in a way that will fool spammers' address-collecting programs but not people who might want to contact you. The most frequent disguise is the addition of the words "no spam," so your address would read
"firstname.lastname@example.org." Experts are now suggesting something a little more creative would be even better.
* Keep your address off any public Internet directory, including your service provider's. Directories are a favorite source for spammers.
* Most ISPs let you restrict accounts so they receive only from screened "safe" addresses. This is particularly useful for children's accounts.
* Spammers often send their mail through "dictionary attacks," where they first try "email@example.com," then "firstname.lastname@example.org," then "email@example.com" and so on, through hundreds of thousands of permutations. When choosing a new e-mail address, resist the urge to make it as simple as possible and instead mix numbers into the letters, like firstname.lastname@example.org. While this will be harder to remember, it is less likely to attract spam.
* Whenever you're asked to surrender an e-mail address at a Web site, uncheck any box that gives the site permission to sell your name.
