Junk is identified by contract, not by name
A verdict is recorded against the contract address, so marking one fake as junk does not touch the real token whose ticker it copied. This matters more than it sounds: ticker-keyed filtering is how a tracker ends up hiding your actual holdings because a scammer reused the symbol.
Signals include whether the token can be priced at all, on-chain security checks against the contract, and whether it appears on vetted token lists.
You have the final say, and it is reversible
Automatic classification handles the obvious cases. You can mark anything else as junk yourself, and you can unmark it just as easily.
Marking something as junk moves it to a trash that shows what was removed and how many records it covered, and anything in there can be restored. Nothing is destroyed.
This is deliberate. A practitioner reviewing a portfolio of this kind warned to be careful deleting transactions unless you are certain what they represent, and an irreversible cleanup tool is exactly how someone loses a record they later needed.
What marking something as junk actually does
- It comes out of your portfolio total and out of the movement lists.
- It stops distorting charts, where a token with a nonsense quantity would otherwise dominate the scale.
- It stays in the trash, with a count of what it covered, ready to be restored.
