Most Snopes assignments begin when readers ask us, “Is this true?” Those tips launch our fact-checkers on sprints across a vast range of political, scientific, legal, historical, and visual information. We investigate as thoroughly and quickly as possible and relay what we learn. Then another question arrives, and the race starts again.
We do this work every day at no cost to you, but it is far from free to produce, and we cannot afford to slow down. To ensure Snopes endures — and grows to serve more readers — we need a different kind of tip: We need your financial support.
Support Snopes so we continue to pursue the facts — for you and anyone searching for answers.
