I've spent the past 2 weeks diligently gathering over 400 Midjourney sref codes from Twitter, compiling them into an easy-to-search collection. Feel free to check out this website; it could come in handy for your needs.
The website has two main functions: one is to support one-click copying of sref codes, and the other is to view details and see full images.
Recommend searching 'sref hunter' on Google to get more information related to the website.
