I'm referring to the ability to right click on a players portrait and click block. Most normal options aren't there, but block and report are. Seeing as you can't normally hear or talk to this person, block shouldn't be needed. Instead, ironically, block allows for the very action that would warrant a block. A block can still be done on that player via chat, if needed. That said, if block is remove from portrait, it won't ever be needed in wvw for players from other worlds. Anet has also made it clear they don't show names so that people can't contact each other. Having block allows for something they don't actually want.
