siteist 

A word that is the same format as the word racism which in analogy describes a certain subculture of users in an app or website that is having or showing the belief that a particular website is superior to another.

This word began when the user @miserable of the app Vent posted about being siteist.
@miserable explained that the users from the website ExperienceProject were being treated like Syrian refugees by some users in the Vent app.

I can't decide which is better between Vent or ExperienceProject because these siteists all have confusing opinions.

siteism 

A 'sitist' is a person or entity (corporation, website etc) that discriminates against websites supporting such a person or entity, based on unfounded assumptions.

Jagex (the makers of the MMORPG, Runescape) doesn't recognise Zybez.net as a fansite for unfounded reasons (apparently there are bad advertisements on Zybez, which don't actually exist), therefore Jagex are examples of siteism, referred to as a sitist.
