That person is creepy.  Can you imagine having the nerve to ask a question like that?  Obviously if they are asking anonomously, they don't have a WHOLE lot of nerve...they just want to be obnoxious.
 
Ignore them.  And forget about it.  I do love the idea of giving them "how things work" as it is completely obvious they have too much time on their hands!  You are so funny, Robbie!
