Twitter is banning political advertising on its platform.
Chief executive Jack Dorsey says it gives people and firms an unfair advantage in sending out highly targeted, misleading messages.
The policy comes in on 22 November, so it will affect the next general election here, the pre-Christmas GE in the UK and next year's US election.
Donald Trump's campaign team has attacked the decision as "very dumb" and "yet another attempt to silence conservatives".
Facebook has been urged to do the same after it revealed it didn't fact-check ads by politicians or their campaigns.
A political message earns reach when people decide to follow an account or retweet. Paying for reach removes that decision, forcing highly optimized and targeted political messages on people. We believe this decision should not be compromised by money.
