If you've noticed that Facebook has begun bombarding you with suggestions to wish a happy birthday to someone you barely know – or like – then you're not the only one; it has emerged that a bug in the social media's notification system has caused this deluge.
Normally you should only get one notification reminding you of a friend's birthday, however people have been receiving numerous emails reminding them to log in and wish a happy birthday.
Although Facebook admits this was a glitch, sending out birthday reminders helps encourage users to sign in, leave a birthday message and engage with the website – which benefits Facebook. Maybe Mark Zuckerberg wished for this when he was blowing out his candles.
Facebook has now fixed the bug, so you should no longer be getting pestered.
