Please let Blacklist work in PvP

[Sinstrel]

I once gave an example of other games where the blacklist works in such a way that you don't even meet in the same group with the people who are added to your blacklist. For some reason, this has been impossible for the SE for many years. But it would be possible to at least give players the opportunity to block this spam. Considering that it is also accompanied by sound signals, sometimes it is simply unbearable.

Allowing blacklist should indeed block messages from that character in PvP. If they allow it to block other players from matching with you though, it would likely lead to players taking advantage of the blacklist to conduct wintrading. (Blacklist everyone currently queing except your friends).
