Biden campaign fury at blocked Facebook ads

Thousands of ads from Joe Biden's election campaign and some from President Trump's have been mistakenly blocked by Facebook.The social network's policy to ban any new ads a week before election day as part of its crackdown on misinformation kicked in on Tuesday, but pre-approved ads should still run.Mr Biden's digital campaign manager expressed fury at the situation.Facebook blamed technical issues, and apologised.In a blog, it said: "We have identified a number of unanticipated issues affecting campaigns of both political parties."Some were technical problems. Others were because advertisers did not understand the instructions we provided and when and how to make changes to ad targeting.""While this impacted a small proportion of the ads about politics and social issues in our system, we regret any disruption in the delivery of these ads."
