"Girlboss" "Gaslight" were the people who made these mods teenagers? …

…Why would you you want to exploit someone just because you do not agree with their opinion? Those names are so cringe they make me want to throw up! Can we just go back to the old system of chatting and forget chat reporting forever?

 # Girlboss
 
-Girlboss is a mod that lets you detect when someone sends a private message to another player and attempts to detect who the receiving player is.
+Girlboss is a mod that detects when people are sending private messages, and who has seen them. This is done by detecting acknowledgements of messages you haven't received via the last seen field.
 
-The detection of someone sending a message is achieved by listening to "header packets" which are sent whenever a private message is sent.
-
-The detection of who received it is achieved by comparing the "last message" field on the receiver's next chat message.
