I am evaluating if hosting a Lemmy instance fulfills my use case. If I share a link with Lemmy, it is really just that, I shared a link, right?! I noticed that in some cases Boost shows further content for this link. For example for a YouTube link it shows a thumbnail. But for other page like news pages it has no thumbnail or so ever. I double checked, if I share the same news article with for example my messenger of choice the preview is correct, means the meta data gets correctly resolved. Because I am new to Lemmy I would like to know which software is now responsible to resolve it. For example I had a NSFW gif page link which was perfectly resolved but others get not.

Every hint about it is appreciated. 🙏
