When ChatGPT cites web sources in it's output to the user, it will call `backend-api/attributions` with the URL and the API will return what the website is about.

Basically it does HTTP request to fetch HTML `<title/>` tag.

They don't check length of supplied `urls[]` array and also don't check if it contains the same URL over and over again (with minor variations).

It's just bad engineering all around.
