Can Tornado Cash be traced?

I'm curious, can you tell me more about whether or not Tornado Cash transactions can be traced? As a cryptocurrency enthusiast, I've heard conflicting information about the privacy features of this platform and how it might protect users' identities. Can you provide a clear explanation of how Tornado Cash works and whether or not it's truly anonymous? Additionally, are there any known methods for tracking or tracing transactions made through Tornado Cash, and if so, what are they? Thank you for your insight.
