A referral link looks like a normal link but contains a unique identification code that tracks who refereed the user to the vendor. Referral links are very common on the internet. Often users are unaware that they are using referral links. Users usually perform web searches, find websites, blogs or forums that contain links to vendors or services that the user is interested in at the time. Often these links are referral links.
Instead of leaving it to random chance who receives a commission, if the user is intending to purchase from a vendor or to use a paid web-service anyhow, the user could consider to use an affiliate link provided by Whonix. This might result in redirecting any commissions to Whonix instead. This is a different type of donation. The user does not have to spend any extra money.
For example, rather than typing fixedfloat into Google, clicking these links and risking that Google or another advertiser earns a commission, the user could support their favorite project such as Whonix by using the referral link provided by Whonix and thereby redirecting the commission to Whonix.
Affiliate links have a risk of moral hazard for those who post referral links on the internet. Competing vendors have different prices and referral commissions. Some vendor might employ practices which are disadvantageous for the user (such as a worse product or service for the same price) to be able to pay higher referral commissions to referees (advertisers). Therefore in many forums and comment sections affiliate links are prohibited, deleted to reduce spam. In the worst case, referees only advertise the highest commission paying vendors which offer lower quality, bad prices or are even scams. To avoid moral hazard, the following affiliates policy is in place.
