As for OP just say "hi" back and do whatever it is you want to do. If people greeting you is a big problem for you then maybe you should join a different fc or none at all. There is currently no way to hide when you come online from fc members, and I don't see this changing anytime soon.

I understand having days in which you want to be left alone, I get those days too. But I understand that people who greet me have no idea how I'm feeling that day and they're just trying to be friendly, so I greet them back and then get on with my life. It's not a big deal, for me at least.
Indeed, you described pretty much what I occasionally did with my previous FC. If someone greeted me I'd say hi and then disappear from the chat. No shame in that, sometimes I just need to be alone and be unsocial. Other times I couldn't stop talking in the FC chat. It's all part of being human.
