I don't see how hacking one delegate can lead to all other delegate being hacked, since I am actually one of Bitshares 101 delegates, and I have no information regarding other delegates, they are all anonymous to me.
I can almost guarantee that likely delegates are found here:
http://bitshares.org/community/team/and than other delegates can be found by prominent users here:
https://bitsharestalk.org/ and Here
https://www.reddit.com/r/BitSharesHumans being social creatures are easily compromised with social engineering and than that can be leveraged by impersonating other prominent members.
uh hate to break it to you, even if you convince me you are Satoshi Nakamoto, I ain't giving you my wallet password or access to my PC dude. lol
