Is anet simply not reading the chat following reports; majority if not the entire server has reported this specific person yet they sign in every day to take out their internal anger on everyone. Most have blocked already but is that seriously the most that anet is willing to do for these situations? All they do is aim to negatively affect other's mental health, occupy a wvw slot during queues, and in general try to obstruct players as much as possible combined with spamming chat. I am certain over 40 people reported this person days ago, possibly hundreds of players reported throughout past 2-3 months.
The current message from anet is that verbal abuse is fine.
Added: Reporting has not worked, we wouldn't be here if it did. Maybe read the reported chats.
