players disconnecting when they loose

Yes and disconnect reports your opponent for "abuse" so he will get banned eventually. Very annoying to wait 5 minutes, why disconnect if you can resign. It makes no sense.

I'm more annoyed when they disconnect when I think the game is even. Makes me wonder what I was missing.
sometimes my internet is bad and then i disconect accidently. It happens.
lefouissimo13 blocked me for what!
I can see that lefouissimo13 has been writing in this thread... (a deleted comment) so that is the reason I am commenting it.
I sure know this thread is about a totally different subject, but I seriously cannot take a player serious when he blocks chessplayers without a good reason. Loosing is not a good reason! But obviously lefouissimo13 thought loosing is a fair reason to block me. I never wrote a single word or letter to him, but after he lost against me, then you just blocked me! I suppose he could not stand a beating and blocks chessplayers that can hurt his moderate low rating (and so is my rating too). Seriously!
I don't understand why some players disconnect the game when they start to seriously loose. Then I am stucked to wait for minutes on the game and that makes me angry.
Ok it says "they may have been subject to blablabla" but they don't care. It is just a game isn't it? And especially in blitz you won't be fighting that long and it is a real learning curve to fight in lost position. Sometimes you may even win because your opponent feels so strong that he can make mistakes in your favor. I guess it is why you have the option to add Friends, I should use that more...
