and since you're talking about the mails (Discord) overlay, so many RP players use the feature to hide the overlay. There is no rule saying that you have to display your discord overlay...

And if you don't know the rules atleast read them first before replying to a forum, as you can see the bug abuse here is the person being shot at and not taking any damage at all. Please Think twice before saying anything cause i don't know what you're trying to prove here

First of all, please explain why do you think it should be considered as meta gaming. since you just said "you are doing meta gaming" Explain the reason or don't put false accusations on anyone like that..
