Facebook recently blocked the phrase “everyone will know” for a few hours on Monday before removing the ban.
On Reddit, it was noted that Facebook users who tried to post “everyone will know” on someone else’s Facebook page would block you from doing so. A number of people saw error messages after typing in the message.

The issue appeared to have ended after only a few hours, but it made waves across Facebook and Twitter.
The phrase likely got caught in the social media network’s spam filter. Also, like Google and Twitter, Facebook doesn’t reveal how its spam filter works out of fear that it will be abused.
“This was a mistake with our spam filter and our engineers have resolved the issue,” Melanie Ensign with Facebook security communications told The Huffington Post.
The Epoch Times independently confirmed the phrase can now be posted.
“We’re constantly updating the rules used by our spam-fighting engine and this particular phrase erroneously got caught in the mix,” she added.
The problem was first flagged on Friday when someone posted a topic on Question.com, asking: “A lot of my friends have been trying to post it and no one has been able to do so. If you try to post it multiple times it will block you from posting any status,” the person claimed.
Users complained they had trouble sending it via Facebook private message.
“We actively fight spam, phishing, malware and any other attacks on Facebook,” explains the site’s Help Ceter.
On Reddit, users discussed the possibilities of what happened.
