So, not really a bug, but I learned tonight that any kind of coding input into chat using "carrot" brackets gets removed from chat. While this makes perfect sense, it also allows for infinite spam if someone were to just copy/paste it.
In the screenshot shared below, I used (test) but with < > and was able to spam it over and over. If someone wanted to troll a chat, they could do so without the error message of "you cannot send the same message twice"
From my chat side: https://prnt.sc/Ejx9nhfgb_ty
From another's chat side: https://prnt.sc/Z9uLKpTeEF06
Edit: for clarification, I did the above in faction chat so as not to share it in a public chat.
Edit2: It ignores spaces and allows the text to exist. IE: < test > will send to chat, but without the spaces, sends a blank message which can be spammed endlessly.
