Yeah, my entire family uses a single hotmail account and practically nothing gets through the filters. We've only ever had one friend start sending us "trapped in Britain" requests, and we've been using that account as far back as I can remember. I'm 16 now, so it may have been as long as 10 years! If anything, the spam filter is a little overactive- sometimes Amazon.com order responses get caught up in it.
EDIT: OK, that's weird (and a little unsettling). I typed "amazon.com" and the forum immediately hyperlinked it. Did that happen on Stardock's end, or could it possibly be something amazon itself does??
