TikTok removed videos after a BBC investigation found stars posting political videos without disclosing that they had been paid to do so by a marketing company.The BBC's Sophia Smith Galer reported that Bigtent Creative, an agency which grew out of Elizabeth Warren's campaign in the Democratic primaries, had been funding posts on the platform.Smith Galer said that Bigtent-funded posts were a mixture of nonpartisan content encouraging people to register to vote, and some videos which explicitly encouraged people to vote against President Donald Trump.The latter category would put the posts under different rules, since they would count as campaigning.Bigtent Creative told the BBC that it gets non-partisan funding, and that the creators' videos should not have had anti-Trump sentiments.The BBC reported that TikTok removed the videos after the BBC flagged them, citing the policy banning political advertising across the platform, and another requiring users to disclose when content has been paid for.The videos got hundreds of thousands of views before they were removed, the BBC reported.
