So since it is not there you have no reason at all to say it works like that (hey that would be dumb, I could also say blocking somebody make it rain goldfish, and it is true since it is not there...). I say that it does what it says, no more, no less, your fantasy imagines that it also does other things for which you lack all proof, and can't even find a single weblink supporting your claim. Posts about people who blocked other players but still run into them due to matchmaking however are for yrs widely spread over the web. So either support your lies or just shut the f up with your disinformation.
