Privacy tools attract convincing clones. There is exactly one place TornadoSol runs.
tornadosol.com (and www.tornadosol.com, which redirects to it). Nothing else is TornadoSol, whatever it looks like.A cloned mixer front-end is cheap to build and hard to spot. It looks identical, because it is a copy of the real page — but the deposit address belongs to the attacker, or the note-generation code has been altered so the attacker can reconstruct your note and withdraw before you do. You would not find out until your withdrawal failed.
It will never message you first, never ask for your note by email or chat, never ask for a seed phrase or private key, and never ask you to "verify" a wallet by sending funds somewhere. There is no support channel that could legitimately need any of those things.
