For weeks, Facebook has been assailed for a policy that allows politicians and their campaigns to post nearly whatever they want, including false and misleading claims. Critics have included Democratic presidential candidates and several hundred Facebook employees.

This week, another critic emerged: Adriel Hampton, a marketer and progressive activist in San Francisco, who on Monday announced his intention to run for governor of California in protest of the policy, posting fake ads to prove his point.

Facebook has since said that it won’t allow Mr. Hampton to take advantage of its lax approach to political speech despite his candidacy, and he says he is exploring his legal options.

[In a stark contrast to Facebook, Twitter said on Wednesday that it was banning political ads.]

Here’s the latest on the social network’s policy and Mr. Hampton’s crusade against it.
