But let me explain. Spam often costs the recipient when Internet or phone access is charged by the minute. Internet Service Providers, too, bear huge costs in handling spam, and pass costs onto their subscribers. With e-mail spam, printing, postage, and address lists costs are no longer limiting. Since spam costs little to distribute, spammers don't bother targeting but just send more.
Business people are often overwhelmed.
Spam is often distasteful, obscene, and offensive. Fears of electronic tracking have raised serious concerns about privacy. As a result, e-mail users, especially a vocal minority, are complaining loudly. States and countries are passing anti-spam legislation. Legitimate business are now expected to post a privacy policy guaranteeing that e-mail addresses will only be used for the purpose given, and not sold to third parties.
