Spam is any unsolicited and unwanted electronic message distributed over the Internet.
When most people hear of spam, they either think of the luncheon meat or of unsolicited emails filling their inbox. While spam email messages are common, email is far from the only medium used by spammers.
- Email: Experts estimate that spam email messages make up more than half of all of the email in the world. Email spam is often used to distribute trojan horse malware, to trick users into divulging private information by linking to a fake web form, to commit money-transfer fraud, or to increase traffic to e-commerce sites.
- Forum spam: Forum spam consists of advertisement-style posts made to forums. The posts have the dual purpose of increasing the number of links that point to the advertised site, as well as to drive traffic from the forum to the advertised site. Virtually all forums have policies in place prohibiting this type of activity, but on poorly moderated sites forum spam is common.
- Text messages: Spam messages sent by text message often encourage the receiver to download an application, thereby incurring fees, or visit a particular website.
- Social networks: Fake user accounts are used to spread spam messages across all social networks. The intent of spreading these messages is to increase traffic to the site being advertised in the spam post.
- Blog, wiki, and website comments: Website comment systems are frequent targets for spam. Messages posted in the comments section of blogs and other websites, like forum posts, serve the dual purposes of increasing the number of links that point to the advertised site, as well as driving traffic to the advertised site.
- Video sharing sites: Spam videos uploaded to sites like YouTube often appear to be about an interesting topic but instead try to get the viewer to click on deceptively titled links which lead to external websites.
