autoreply & ignore hidden users

[Florin Andrei]

Is there a way to ignore only the hidden users, while also sending them 
an autoreply?

I find it annoying when people stay hidden and all of a sudden start 
chatting. I want to automatically send them a reply saying:

"Because you are hidden, my IM client is ignoring you. Please change 
your status to visible and I will reply. Thank you."

Basically, just "show your face or I won't answer."
