It's not as simple as that, they can always detect and determine where their members are, as many Instances both in Skyrim and Oblivion have determined.
Their pact with Sithis and the night mother is eternal up until expiration of life, and Sithis, as well as the spectre of him would likely not wane, he is not like the Dawdric princes where the strength of the DB matches his own, he simply is, as well as this he doesn't prevent the dissolution of the DB, even though the Skyrim faction is remaining strong, irregardless of Ciceros plans; if the listener ever arises that is.
Sithis will still punish his own when they disobey, and whilst there is no evidence to suggest that the wraith if Sithis is aligned to him, even though it's name should suggest that it is, there is no proof to disprove that fact either.
In the end, I recommend that the Bio be modified to a more agreeable basis, one can be an assassian that is unaligned to the DB and still be as equally efficient, the Morang Tong are a perfect example, although, I do believe that one must be a Dunmer to be apart of that, I'm unsure of the specifics.
Well they find their members cause they are good at that. I doubt it's magical in nature like they just instantly know. I doubt it.
Yet there is no real proof of Sithis intervening as he hasn't actually shown himself or truly spoken. Everyone speaks for him like many worshippers speak for God in our own reality. I've researched extensively and never found a hint that Sithis, himself, keeps the DB going. Its more so that his followers and the Night Mother that does. And it is called the Wrath of Sithis but lacks evidence that he himself drops that wrath upon his followers. As with Astrid, who went against the Night Mother, she was done in and remarked she screwed up and preformed the ritual upon herself which can be considered the Wrath taking affect even though Sithis himself never stepped, so to speak.
I'm not even arguing for my character so much as just lore in general. Lol
