Images in Signatures

As long as I care to remember images and gifs in signatures was a no-go. I’ve seen a bunch of newbies with obnoxious gifs in their sigs that have yet to be reprimanded. Can I start pointing mods to snipe these people or is it not a thing anymore (I doubt that since this is murder for people on mobile)?

in your profile > signature settings

you can disable all sigs or just images in sigs
