Content recognized as deceptive or problematic had been mistakenly prioritised in customers’ Facebook feeds lately, because of a software program bug that took six months to repair, in response to tech web site The Verge.

“Unable to find the root cause, the engineers watched the surge subside a few weeks later and then flare up repeatedly until the ranking issue was fixed on March 11,” The Verge reported.

But in response to Osborne, the bug affected “only a very small number of views” of content material.

That’s as a result of “the overwhelming majority of posts in Feed are not eligible to be down-ranked in the first place,” Osborne defined, including that different mechanisms designed to restrict views of “harmful” content material remained in place, “including other demotions, fact-checking labels and violating content removals.”

Under the programme, which began in December 2016, Facebook pays to make use of reality checks from round 80 organisations, together with media retailers and specialised reality checkers, on its platform, WhatsApp and on Instagram.
