Agor.io

Similar to most screamers, this page displays a flashing picture of Jeff the Killer along with an ear-piercing scream, and if you try to close the page a pop-up with "YOU SCARED BRO LOL" appears. At the top of the page, it says "AGAR.IO LOL" Meant for people who accidentally mistype the popular game "agar.io" People with epilepsy should not look at this page and try to be careful when typing agar.io

Close inspection near the scrollbar, you can see gray text that reads:

"L3mm1ng, Braz1l, App3r, Yazir, Alyx, WanR00t, H0rs3, D0nny"
