This is getting past the point of manageable. Either fix the bot problem, expand blocked player list to unlimited or lose your player base.
100 players clearly isn’t enough to report and block EVERY bot since none of the game staff is willing or able to fix this.
you can empty your block list after 30min-1h they are gone by that time. And yes you can turn of private messages if you create a new tab.
And yes smile and ags is doing something about it.
You can technically uncheck the box for whispers so that you don’t see whispers.
