Well, here's some technical news about Microsoft and their mostly-used software "Windows Live Messenger"
It seems that Microsoft filters words and website-urls you want to give out to your friends; words like Scream/scrap/info etc are not viewable by your friend or contact who's chatting with you.
I've some proof what I tested on messenger today, and it seems it does filter those websites/words. Too pity that there isn't a list of words/websites what's filtered, but that's for a technical reason what I understand. The proof of the filtering can you see on the next screenshots:
