I Play mostly Deathmatches and i'm using 1.3.1. But when mosly on every server i get banned after a few min, it's totally random when. I'm not using any kinds of cheats or hacks and i got 8Mbit connection. And I keep getting banned on servers, why?

How high is your ping?

It's between 23-50 pending...Haven't never been any problem...Some Servers never kick me, some always..

this used to happen to me. But only when i played on servers, where ranking nick registration was on. you play in such servers?
