Blacklisting should be a two-way street and isn’t.
One person can blacklist another but once that initial blacklisting takes place, they can just toggle it on and off and harass another player remorselessly and the other has no choice but to endure their petty banter while a GM report goes absolutely nowhere and reverse blacklisting isn’t even remotely possible when the players prewriting messages, sending them and then instantly reblacklisting.

Good job making it easier for people to harass each other knowing there isn’t enough resources to get GMs to combat bullying and blacklisting was meant to be that failsafe and now isn’t.
