My miners are just doing their job filtering out spam, like they're supposed to as part of the Bitcoin system.
My understanding is that SD no longer creates 1 satoshi transactions. The minimum it now sends is 5000 satoshis, which should help with the unspendable bit dust problem. Does that change your position on SD transactions?
Not at all. Those are still dust spam, and even if they never sent anything on losses, their "bet" and "win" transactions are still spam.
