Is it common to have tons and tons of names on your blacklist?

[Fyrebrand]

Mine is completely empty but I never build friendships in game to begin with and couldn’t care less about what someone might yell around me

Same here. I just play the game and do my own thing. I used to blacklist RMT spammers, but there is literally no point since it seems to be a different account every day and I don't spend that much time idling in town to care. Just report and be on my way.

Very occasionally I'll see some problem behaviour being shouting in map chat, but even then I don't blacklist. Annoying or not, I prefer to be aware and not blind to what's going on.

That said, I've seen some threads about players who have serious issues with targeted harassment and stalkers, and Blacklist does almost nothing to help them out. I think the feature needs to be strengthened in this regard.
