What is dust attack? I use sparrow and curious what to look for. Thanks.

Tell us simpletons what you mean ☮️

wouldn't it be better to just sweep it with a zero fee tx?

per maple AI: Privacy Degradation (Chain Analysis): This is the primary goal. By tricking users into consolidating dust with their other funds, attackers (often chain analysis companies or surveillance entities) can link multiple Bitcoin addresses together, building a map of which addresses belong to the same wallet or user. This erodes the pseudonymity Bitcoin offers.

I used to get a lot of dust attacks, you're making me wonder now if i'm a target lmao

People send you free money hoping that you use it so they can track you

I spent the one I received via op_return, so that I would not accidentally spend it even if I use a different wallet app
