Because of this, the ban is unlikely to have
a big effect on overall political advertising,
where television still accounts for the majority
of the money spent. In digital ads, Google and
Facebook dominate.
Unlike Facebook, which has weathered most
of the criticism, Google has been relatively
quiet on its political ads policy. It has taken a
similar stance to Facebook and does not review
whether political ads tell the truth.
Twitter, Facebook and Google already take steps
to prevent political manipulation by verifying
the identities of some political advertisers —
measures prompted by the furor over Moscow’s
interference. But the verifying systems, which
rely on both humans and automated systems,
have not been perfect.
