Honda's move comes amid Facebook CEO Mark Zuckerberg's attempt to address advertiser concerns in a live question-and-answer session on Friday, where he announced minor changes to Facebook's ad and content policies.

Zuckerberg said there will be no exceptions to these policies.

Facebook will also be banning any future posts that spread any false information about election process or the local polling conditions.
The campaign has called on Mr Zuckerberg to take further steps, including establishing permanent civil rights "infrastructure" within Facebook; submitting to independent audits of identity-based hate and misinformation; finding and removing public and private groups publishing such content; and creating expert teams to review complaints.
