A good or bad idea to ban ads?
Twitter is stopping political ads on its platform after concerns they could be used to spread misleading information.
The company says the reach of political messages "should be earned, not bought" and the ban will come into force from November 22nd.
Twitter boss Jack Dorsey says online advertising can pose a "significant risk" to politics.
This move has been praised by many social media users who are annoyed at the disinformation currently being spread in Facebook ads and many speculate that it will pressure Facebook to change its own rules.
