@Hanna_Brassheart @Jacoby_Elderfun1 @Iliara_Mustardtop I have a suggestion.
Next time someone posts a photo or a GIF with a link on it, you could follow the link, find the GIF, download it onto your computer as a file, edit the person's post, replace the link with the downloaded file and -- of course -- warn the user.
I don't know if following a linked GIF would be safe or not buuuuuut. . . you don't have to follow my advice hahah.
