On Twitter, 6,000 tweets are published per second on average, or 500 million tweets every day. How many of these millions of tweete💎rs, when they retweet, are thinking about defamation law? It may or may not be illegal for you to retweet someone else's defamatory tweet depending on the country. Defamation, to put it simply, occurs when someone publishes a false, unfounded, andꦿ reputation-damaging remark about another individual.
