The attacker (see here) is back:

He's spamming Just-Dice with tens of thousands of tiny outputs presumably in an attempt to disrupt staking.

If you're staking CLAMs please check whether he's attacking your wallets too. You can set "mininput=0.01" in your clam.conf to tell it to ignore UTXOs worth less than 0.01 CLAMs and that pretty much defeats the attack.
