How to identify fake USDT?

I've been hearing about the rise of fraudulent USDT tokens lately, and it's really got me worried. How can I spot a fake USDT? What are the tell-tale signs that a USDT token is not legitimate? I've seen some offers for cheap USDT on unregulated exchanges, are they likely to be fakes? Should I only trust official platforms like major exchanges for buying and selling USDT? And what should I do if I accidentally come across a fake USDT? Is there a way to report it? I'm really trying to stay vigilant in this crypto world, but it's tough to navigate sometimes. Any advice would be greatly appreciated.
