I dont spend time searching Ips... but even if i did i dont think it would matter because i think most of you polish have dynamic IPs.. and maciek has talked about using VPN's. I imagine (im not sure because i dont check) Claw uses VPN's also.
if you play someone 30 times in last 5 days, and then they suddenly start playing very different at a much higher skill, why check IPs? I dont see the need.
(A)Mystical beats SPB 74-33, (B)SPB beats harry wangs 8-2, (C)HarryWangs beats mystical 3-1.
lots of situations with different players just like that.
