It’s probably because something your instance admins did. For me it didn’t show up either, so i looked at the link:
https://lemm.ee/api/v3/image_proxy?url=https%3A%2F%2Fi.imgur.com%2Fi2IzTtY.png
And it responded with 429 “Too many requests”
But the url is clearly pointing to imgur, why the middle-man? Just urldecode it and here ya go
There’s an OS you might like. It has no UAC, no file permissions, no sudo nor chmod, as it has no multi-user support, no antivirus and no firewall, no protection rings, not even spectre/meltdown mitigations, and most of all - no guard-rails whatsoever: You can patch the kernel directly at runtime and it won’t even give you a warn. And yet, it is perfectly safe to run. It’s called TempleOS and it achieves such a flawless security by having no networking support whatsoever and barely any support for removable media. If you want a piece a software - you just code it in, manually. You don’t have to check the code for backdoors if it’s entirely written by you… only for CIA at your actual back door…
