@_elena There are definitely accounts here that post #AISlop images. Many of the ones i see are using them along with the #infosec hashtag which i follow.
While it's certainly better than many other places, there are people who for some reason or another will post links to articles, blogs or whatever and instead of allowing the link preview to generate, will add some AI image.
Usually these are very small accounts here doing it, but i've muted a few large ones doing it as well.
