The problems seemed to occur because of a bug in the update that Facebook rolled out today. The bug apparently affected only those posts which contained links to the content outside of Facebook. The bug affected Facebook’s image-scraping system, which automatically pulls pictures from posted links. The image-scraping tool is supposed to help users present links to other content with a photo from the site they are linking to. The post, complete with picture, then appears friends’ timelines. Users attempting to post new links were met with a security warning because of the bug. Some users who clicked on existing links faced similar warnings, which read that the link has been blocked for security reasons. Many posts containing links also vanished. The hardest hit by the bug were small and medium business owners who use Facebook to promote and sell their content. They took to social media and were particularly vocal about the impact on their businesses.
Facebook said that they have resolved the issue and the remaining affected URLs are being unblocked. “We’ve resolved the issue and the remaining affected URLs are being unblocked. We apologise for the inconvenience this has caused,” Facebook stated.
