I was trying to make a userscript to filter out more than one tag at once with ?exclude= but i ran into this error:

If this is intended behaviour and fetch shouldn't be able to GET a game's page from the https://itch.io/games origin then why is it returning 200?
This is the code:

let gameLinks = document.querySelectorAll(`[class="thumb_link game_link"]`);
fetch(gameLinks[0].href).then(res => console.log(res));

image isn't showing up on firefox but is there when i try and edit the post so i'll just add an imgur link to it just to be safe: https://imgur.com/bDBl3Oo
