I've been getting tons of dust transactions to my wallet, 0.00000546BTC every month or so.  I'm trying to understand the whole reason for these attacks. So, they trying to deanon wallet users and then what? Unless federales doing that how it benefits non govt entity? Either way I don't want to take any chances. I'm using bitcoin core wallet is there a way to mark these coins as bad? Or tell the wallet do not spend?
