A dry erase signature wall at Facebook's Menlo Park, California, campus drew the attention of founder Mark Zuckerberg.
Employees have reportedly been crossing out "black lives matter" and writing "all lives matter."
An internal memo was sent across the company from Zuckerberg acknowledging that employees have in fact crossed out the slogan and replaced it with another.
The memo was posted on a private company announcement page on Facebook and obtained by technology blog Gizmodo.
In the memo, Zuckerberg made it clear that he found the practice unacceptable in another meeting and that he is disappointed that this has continued to happen since then.
The full statement can be read below.
"There have been several recent instances of people crossing out 'black lives matter' and writing 'all lives matter on the walls at MPK.
"Despite my clear communication at Q&A last week that this was unacceptable, and messages from several other leaders from across the company, this has happened again.I was already very disappointed by this disrespectful behavior before, but after my communication I now consider this malicious as well.
"There are specific issues affecting the black community in the United States, coming from a history of oppression and racism. 'Black lives matter' doesn't mean that other lives don't -- it's simply asking that the black community also achieves the justice they deserve.
"We've never had rules around what people can write on our walls -- we expect everybody to treat each other with respect. Regardless of the content or location, crossing out something means silencing speech, or that one person's speech is more important than another's. Facebook should be a service and a community where everyone is treated with respect.
"This has been a deeply hurtful and tiresome experience for the black community and really the the entire Facebook community, and we are now investigating the current incidents.
"I hope and encourage people to participate in the 'Black@' town hall on 3/4 to educate themselves about what the Black Lives Matter movement is about."
Two percent of Facebook's employees are black, according to the latest data released by the company. Fifty five percent are white, 36 percent are Asian and 4 percent are Hispanic.
Time reported that the company began an anti-bias course for employees last August to promote diversity.
