According to this http://playdota.eu/forum/index.php/topic,25525.0.html , your favourite pain in the arse is here with another post! And I think I should title this thread "WILL YOU PLS PREVENT LEAVING FOR CONNECTION LOSSESDo you think it is ok if you screw game for other players because YOU are not able to get proper connection? I think it is not. Not that he even is upset by fact he has to request unban, he shouldn't be unbanned at all!
And I am not even talking about liars that unplug on purpose and are being unbanned constantly.
Rules should change about this.
What about:
Maximum no. of internet falls in one week = 1
Maximum no. of internet falls in one month = 3
Maximum no. of internet falls in last 6 months = 10
If you excess, you will be considered as leaver.
I think this would rapidly improve games quality, force players to fix their connection (but, actually, there are no players with bad connection, they all are IMHO lying unpluggers) or to change (or slap) their providers.
Cheers
