I think this is still true. The only saving grace of the current blacklist system.
I feel like you haven't been playing this game for very long, or that you're lucky for not running into the types of people that we blacklist. You know, the ones who yell at new people for getting hit by AOEs and kick up a fuss about wipes on old content. Heck, I had a tank refuse to pull in one of the new raids because we wiped a few times on the release day and then we had to kick him.
And then to get the same people when we queue up for something else makes us feel like the blacklist is useless.
