blacklist is such an ultimate move though (I RARELY used it in XI because I never knew it down the line that person was doing an event/story/etc that I really wanted to get done). So me personally blacklist is a waste of time (unless its the extreme where you've contacted a GM and etc over it).

Regardless as it stands now, /anon is pointless (literally pointless it has no value to be in the game right now) with a search function it definitely has a purpose, a good thing to point out is the crafting classes (since we'd be able to search for them) in order to sell something in the wards the gear must be @100% durability, which only a crafter can do, say I don't have a craft to a certain level so I do a search for level 40-50 weavers, I'd just go down the list asking for a repair, now that that instance times a hundred (because I'm sure I'm not the only one that will do it).

If you want to craft in piece you will HAVE to have /anon, same goes for combat classes as well, people are going to need healers/tanks more than anything so they will get random invites, /anon will stop that from happening. Maybe it didn't happen a lot for you (hypothetical you) in XI or XYZ MMO but it does happen quite frequently, ask any bards from XI lol.
