My guess is that devs speak with each other and Nxtl devs consulting with Nxt devs.
As for fighting puppets I posted some thoughts in this thread and was totally ignored. I've got not a single answer from devs. To be honest I'm tired to shout in nowhere. I suggested some measures to Utopian but was ignored. At least he didn't accept payments from exchanges. Now Nxtl devs don't even want to forbid sending payments from exchanges although I posted an image with taint analysis which showed that 11% payments were made from Bter. I don't want to post comment with huge red letters, I'm sure they've read it but didn't take them in consideration.
We do not ignore, we changed the rules before registering (

Yeah, but what about payments form exchanges? It's probably the only thing you could do to prevent buying several stakes.
