Why do MLS photos get Fortnite screenshots added after the home sells?

This is the third or fourth time I’ve seen a home get the exact same random Fortnite pictures added to the MLS photos after it sells.

Is this a privacy thing? A glitch? Anti-SEO? It didn’t have this before the sale.

For example: https://www.redfin.com/IL/Hinsdale/119-N-Grant-St-60521/home/18033227
