We have a ping limit of 300, and allow people from South Africa and Australia (their ping is always around 300) to remain on the server as long as their ping remains stable, as they do not cause any significant lagg.
We do try to make all people with unstable pings leave, and generally we have pretty stable pings on the server. When any serious connection issues appear, it's usually due to something going on with the server itself.
But thank you for the suggestion, and it's great to see you in our forums - you should stop coming in with an alias all the time on the server as well
