A 35-year-old man in Sweden appealed for donations to the Islamic State (Isis) terror group using statuses posted to his open Facebook account.
The messages remained online for over two years before the social media site reacted, reports newspaper Expressen.
Facebook eventually deleted the posts after being contacted by Swedish police security agency Säpo.
"We remove all content that is in breach of our rules when it is reported to us. On occasions we make mistakes. When that happens, we correct them as soon as we are made aware," Facebook Nordic head of communications Peter Münster told the newspaper via a written response.
According to the report, the man wrote in 2013 a message saying, "Contact me to support your brothers at the front".
