That tagline is completely false, it was made with our partener project, Buzzr - The Buzzword Generator!
"Pls No More Emjois" is a Facebook chat spammer that exploits one key vulnerability: Facebook spam cool-downs don't exist when sending Emjois or Stickers. If you want to send your friend the word "Lol" five hundred times, Facebook will give you a cooldown and eventually a captcha when sending messages! But what if you want to send your friend a Pusheen sticker five hundred times? No problems there - and Pls No More Emjois makes it easier than ever.
