There are a couple of threads today I've been temped to slap the Wall of Information into. It wouldn't have looked out of place at all. lol.
I also don't get why some folks are adamant they are going to try and force themselves onto people who don't want to interact with them.
But then again, I have no issue with players asking others players for good trade routes, sightseeing tips or a list of names of people to throw on a block list.
Because it's not that simple, the block function doesn't just mean you can't see the player, it's that you the blocked player can't instance with anyone else that's also with said player. If there's an instance with 20 people and just 1 has blocked you then guess what, you get empty instancing. What SHOULD happen at most is that the blocker is invisible or otherwise kept free from those that they block, and even that seems to be an abuse of a feature meant for harassment and not for using Open to keep only weaker players around to pick on.
