It was less than two months ago when I did my research: https://bitcointalk.org/index.php?topic=1077613.0 There are 1,800 active listed, but if you check the dates of the last transaction, you can see many are from months ago--before there was a list of holdings (1000+ meant active, but most weren't --more than half if I remember correctly), but now that and the hosting company's name is cut off--I'd like to think it was a reaction to my research--you don't want the suckers knowing too much about the going-ons.  


I do like how you create a fake satoshi reply, dismiss the attack vector without any analysis, and misrepresent the real number of active nodes, but I don't expect research or formal arguments from dashers. If you don't think law enforcement would coerce or subpoena mn operators (you'd only need Evan or Otoh for million dash) or hosting companies to comply in orderto break up a pedophile-mining ring or a drug syndicate or human trafficking operation, then you haven't been paying attention with how well LEAs orchestrate international sting operations--though again, they would only need one or two whales and they'd have enough to undermine anonymity and it could be done by one domestic agency.

It's an attack vector and it won't disappear until you get rid of masternodes or find a better way for them to create anonymity.
