But what can we do about it ??
I think just be aware if it. And if there is an AC you want to be in contact with, contact them directly and dont assume that just because you are getting cards signed from them from their parents address, that that is the AC's correspondence address, unless you are sure they livs there. Only reply to the person or people you KNOW lives there, and if you are fond of their AC try to find out their address or phone number and drop them a direct line.
God knows how many other people have thought that my DMs address was my correspondence address over the years, I only know about the ones I know about! I once broached the subject with her and was told that it was none of my business.
There may be other people who thought they were keeping in touch with me by replying to the address that the cards from "me" came from? Who knows?
