Doubt it, it would be possible to play 17 games each day. So if you played 17 games and played them 3 times... that would be over 50. Which shouldn't get you iced. I am curious where this source came from.
False rumour, high likely. If this is true, that would mean that all people who use a SS with 300k lists would be iced.
Yeh it's not true. I remember one day I played hardcore and got loads of scores sent (at least 50) and I haven't been iced.
