What is the worst source of information?

The worst source of information is typically considered to be unverified or biased sources, such as social media posts, personal blogs without fact-checking or credible references, unmoderated online forums, biased news outlets or websites, or information coming from untrustworthy individuals or organizations with a vested interest in promoting a particular viewpoint or agenda. It's important to critically evaluate the credibility, reliability, and accuracy of information before relying on it.
