As it stands the blacklist only blocks users from PMing you. But this seems silly, as your blacklist is also your ignore list in game. This would be like making it so the ignore list in game only blocks users from whispering you. It still does not block the horrible content which they would spew in public chat.
So many people voiced their desire for a full ignore feature, and all we received is this... to be blunt, half-assed feature.

Please make it so that we can ignore certain users. In the long run, it will make it easier for sentinels so that users who are flamebaited cannot react, et cetera.

Thanks.

It's been requested so many times on old forums, would have thought it comes by default with the new one. Or maybe the function isn't working properly. Either way, would be much appreciated.

nah it was confirmed for me it's just to block PMs
which is bloody stupid

That's dumb as hell...
