I have created a facebook like button in my custom created site. so you know people can share the site to their friends. and to my surprise facebook sent an alarm to my facebook account telling me that my FB had been hacked and demanded me to download their app for cleansing the infected malware.
and now I can’t open my facebook account in my computer anymore and I can only open it in my android smartphone. so yeah if you ever in need of a way to stay off facebook for a while then you can use that link to click like and facebook will hate you for it.
in conclusion, it’s better if you don’t get too attached with facebook. better to just live your life in wordpress or other website that you can control.
