The Personal Avatar (aka Pavatar) is a personal picture used by other websites to display whenever referring to content provided by YOU, the user. An example would be if you made a comment or a site posting where an online is required. This way, delivering your Persona is peripheral and can be (nearly) anonymous. This option inhibits companies from collecting personal information about your habits on the web.
Why should I use Pavatar?
Pavatars are a great and open alternative to other resources and makes you independent by providing open information.
Pavatars have all advantages of Favatars, but are bigger and you can use different Pavatars on one domain.
Because everyone uses his/her own Pavatar on his/her own page, there is no need to sign in on external resources.
