uhhh isnt that sort-off creeping and hipocritical(is that even a word?) anyways I think its be pretty rude to be online but appearing offline to all your friends I mean whats the point on being online then? just spying on your friends? I hope this never happens -_- altho I have *you must be this old to be my psn friend rule* most people would abuse the "invisible status" just like they do on messenger.
I'm no troll, I just dont like you.
If I'm understanding the OP's request correctly, he wants the option to be invisible to his 'friend list', as in, not have it pop up a notification telling friends on his PSN account that he is currently online, and not the option to actually have his avatar be invisible in Home.
PS: I cleaned up the off-topic posts.
