invitations spam

This is what I am seeing everyday when I log into Windows Live Messenger

I am imploring the Windows Live Team to do something about this obnoxious problem. Blocking and ignoring is counter productive. I cannot do this every time I log into Windows Live Messenger. Its frustrating sifting through good and spam. I am not denying that other Social Networks such as Facebook and My Space also face this issue, but not to this extent.
