From my tests:
- pasting a gif image is broken
- uploading a gif image works
- pasting a gif url works fine
- copying tenor links is unreliable due to their hotlink protections
Discussion
btw is there a way to remove media from a note?
on the mac version of the damus app rn and i canβt see a way to remove it (ignore the first pic, itβs still on here but i canβt delete lol.) 
Hotlink protections?
