I'm not saying they found out where you were using OOC means, there's no evidence of it, but for the sake of argument let's run this down as if it were true.

You give your location away on Discord.
You are surprised that someone comes and attacks you.

Now, this would be foolish in CF as is, but on top of that..

You doxxed your own character.
You are a massive faggot that whines about everything.
It's hilarious to troll people like you.

Why is this any surprise at all to you?
