I just saw this article.

https://thenextweb.com/apps/2020/03/04/its-painfully-easy-to-see-whos-liked-you-on-tinder-without-paying-for-gold/

According to the article, Tinder is using CSS, filter: blur(12px;).

This totally makes sense for a web application since generating masked images would need some work.

I checked the web app and knew that Tinder is using react and it prevents accessing the Who's Liked page directly.

1. Go to https://tinder.com/app/recs
2. Go to https://tinder.com/app/likes-you by clicking the photo in the sidebar
3. Open Chrome Developer Tools
4. Paste the following code on your console

const getPiclinks = () => {
  const all = document.querySelectorAll(".StretchedBox");
  const start = all.length/2; // divide by 2 because StretchedBox class is also used by the div in the side bar 
  const end = all.length;
  for(let i=start; i<end; i++) {
    const url = all[i].style.cssText.replace('background-image: url("', '').replace(")", '');
    console.log(url);
  }
}

1. Run the function
   type getPiclinks on your console

2. Click the links console shows
   You will see links to the image.
