I can't believe I'm about to publicly post this.
What is it you want to post publicly?
I'm posting some confidential information on my friend's identity.
If it's something confidential to a friend then you shouldn't be posting it online because that will be there forever. You need to make sure that you've sat down and fully thought through what you're going to post online.
Whatever man. It's just a fucking blog and this person has done some pretty fucked up things.
That doesn't make it okay to dox them. You should call them out to their face if they are doing messed up things to you, but this could ruin their life.
