I'm pretty sure I've signed in a few times recently with HEN enabled, didn't run into any problems? Will try again next time I boot up my ps3 just to be sure. Will also mention I've been using it offline specifically for multiman / FTP. If I want to sign in to PSN I just enable HAN instead and play all my HAN content. I'm certain I've signed in at least twice before enabling hen or after enabling hen though. I'm not too concerned about being banned either though, all I need PSN for anymore these days is Dark Souls lol. Netflix works on my system without PSN, could never understand why either. I never installed a nopsn pkg maybe I'm just a lucky one lol..
