So in light of the recent test of ActivityPub on Threads.net I thought I would share how to block threads.net. If you're on a server that blocks it this isn't needed, but if for whatever reason your server won't block it, here's how you can.
Go to your settings and click Import and Export and the import section.
Either create a text file with the meta Domains you'd like to block (one domain per line), or you can download this one I created. (Has Facebook, Insta, and Threads) https://files.catbox.moe/r88lj0.csv
On the import tab upload the csv or text file and import it as a blocked domains list, make sure you're doing it as a merge or you'll lose the ones you already have.
Afterwards you will have successfully blocked the threads domain which will stop you from seeing threads content when they do open federation and make following attempts from people unable to follow you without approval.
Hope people find this helpful, if you do please share so it may help others.
