Immediate Abandonment.

Why do some people immediately abandon a game, which I have selected in the challenge list?  Surely this is not good etiquette?  If they haven't got the time or the patience to play then they should not set-up and offer a challenge.

sometimes a player abandon's your game when they see your rating. At least that seems to happen on some chess sites i have been on. Some players won't play someone 100 pts or more lower than theres 'cause if they lose their rating goes way down...

It happens to me sometimes when I want to play a certain person but a split second before I click on the game, it changes and I end up playing someone else who is rated higher than what I want.
