Facebook admitted Sunday that it had blocked links to the Wikileaks trove of emails hacked from the Democratic National Committee.

In a Twitter post late Saturday, WikiLeaks accused the social media giant of “censorship” and gave its followers an online workaround, saying “try using https://archive.is.”

The WikiLeaks allegation followed a firestorm of controversy that erupted earlier this year when former Facebook workers admitted routinely suppressing conservative news.

In response to the WikiLeaks charge, another Twitter user, @SwiftOnSecurity, chimed in that “Facebook has an automated system for detecting spam/malicious links, that sometimes have false positives,” which prompted a response from the company’s chief security officer.

“It’s been fixed,” Facebook CSO Alex Stamos tweeted.

Facebook didn’t immediately return a request for comment.
