Samouri Wallet and a few others seem to be calling it a "dusting attack", designed to link addresses together through the use of multiple UTXOs from different addresses.

That *might* be going against the message that people should mix their coins using your site since you're the one reducing their privacy for advertisement.

I do not see any information leak in the "888" UTXOs since they are sending them to so many addresses, the addresses are only related as a large arbitrary class (all addresses above a certain value threshold, etc.) and they not attempting to "tag" all addresses in a specific wallet.

All this does is link all the dusted addresses back to their sending address, which is well known and is dusting the entire UTXO set in a known arbitrary way.
