i was playing in fighting games lately and i see sometimes a red label over over there battle tage name and its label them as a leaver or disconnects . also i see them get into games with other leavers / disconnected players matches for a few games so i was wondering if you guys can take this idea as a reconsideration.

We'll definitely take the idea into consideration. Our philosophy has been that we would rather not have leavers playing the game at all (especially in Competitive Play). We keep increasing the penalty for leaving and will continue to do so. We're in the process of implementing a new policy which would take into account how many Competitive Seasons you have been banned from and at a certain point, prevent you from playing Competitive ever again.

Since this post, permanent bans have since been implemented into Overwatch. Read more on this policy here.
