@utopify_org Hey, Good question. I thought a lot about this. It's because of five good reasons:
1. Bandwidth (with many visitors, hot-linking them to all instance all the time is pretty heavy)
2. Privacy. Hotlinking them would give also log to instance owners of who connect to my website.
3. Loading speed: waiting for all servers to get pictures.
4. Copyright, and/or trolling possibly with p0rn or gore.
5. Aesthetic: I love the cat avatars https://www.peppercarrot.com/extras/html/2016_cat-generator/index.php 🙂
@davidrevoy wow, okay, a lot of stuff I wouldn't even thought of until I would run into it.
Thanks for the explanation.
