I found a userscript to automatically redirect any (well, most) Fediverse link to your home instance. Seems to work pretty well.

Sounds great! How do I install it?

If you go to the link, there will be an install button. Note that you will need a superscript manager for it to work properly, though. I recommend Violentmonkey.

Alright, didn't know that I have to use Violentmonkey. Thank you!
