Just to be clear it's only discordapp.com (not discord.com) but of course that could become a redirect at any time. The referer sent by my browser to request the image was forum.brickadia.org (no further path information) so that's better.
It's an ancient problem on forums. Now imagine I embedded an innocent image from brickadia.com and now they can see the IP address of everyone who opens this page.
If you embed an image using "Add an image" it appears to be the same issue. (I posted an image for a second)
