The implementation of affiliate marketing on the internet relies heavily on various techniques built into the design of many web-pages and websites, and the use of calls to external domains to track user actions (click tracking, Ad Sense) and to serve up content (advertising) to the user. Most of this activity adds time and is generally a nuisance to the casual web-surfer and is seen as visual clutter. Various countermeasures have evolved over time to prevent or eliminate the appearance of advertising when a web-page is rendered. Third party programs (Ad-Aware, Adblock Plus, Spybot, pop-up blockers, etc.) and particularly, the use of a comprehensive HOSTS file can effectively eliminate the visual clutter and the extra time and bandwidth needed to render many web pages. The use of specific entries in the HOSTS file to block these well-known and persistent marketing and click-tracking domains can also aid in reducing a system's exposure to malware by preventing the content of infected advertising or tracking servers to reach a user's web-browser.
Wealthy Affiliate is also very strict on spam, which in the end is a GOOD thing, but I have to be careful sometimes about promoting my sites or referencing them. Sometimes I do have valuable information on my site that I think could help people during live chat sessions or Q&A’s, but I don’t share because I don’t want it to look like I’m spamming. They do allow people to promote their sites in certain areas, but in order to keep the community from filling up with self-promotion spam, there are times when it is best not to share certain information from outside sources, especially my own sites.
