tbh if u respond negatively to trying to mess with exploits then i think youre trying too hard to get a reason to be angry
i tried loving with it too, its just fun for some people to find exploits in websites. lmao i changed my fullname to some stupid meme in the official highschool register because of such simple website exploits. this stuff was even more tame than that, the page didnt stretch, hell the majority of users use Swollow's skin and it doesn't even work there.
not to mention you couldn't even change the "glitched" avatar, although it probably wouldn't take long for someone to find out.
