But the real question is why haven't you distrusted silverfuture yourself, yet you ask others to do so for you?
I'm not in DT1 and silverfuture is not in my trust network, so my exclusion wouldn't mean anything. Also this does nothing "for me".
You're not in DT1 this month, why not add them maybe in the next election you will be in DT1 so it will have an effect.
here I added ~silverfuture to my list (as DT1). OgNasty has been on my ~ list since before
