To prevent being spammed, do not publish your personal e-mail address on public sites. Be very cautious of publishing your personal e-mail address on Internet. When you use chats, forums and surveys try not to publish your personal e-mail address if it's not necessary. Usually people who use spamming as advertising tool collect the e-mail addresses from almost every possible sources so its highly probable that your e-mail address would be added to spamming mailing list if you are incautious of publishing your e-mail addresses on public sites you visit. To no longer receive spam, e-mail the network administrator of the network from which the spammed e-mail has come.
