I just wanted to bump this
Usually as soon as I log on I get 10 people starting chatting with me instantly.
I hate being impolite and I usually try to at least give a short reply but it is not always possible - especially when I just want to dress up, which can take a while even without being disturbed
Wouldn't it be a good idea to just add some sort of invisible mode (maybe just visible to people on your friends/lover/spouse lists)? This way one could also just enter the game and maybe search for someone without getting instantly spammed.
