That is really shitty man. We aren't children on the playground gossiping about each other. Why would you post on the forum without first talking to the person you are accusing and asking them wtf is going on? You are no better than every fucking whiteknight SJW posting on tumblr. People like you make me sick.
Grow up and stop acting like a kid. Just send the dude a message and tell him what you're worried about. Are you so scared of him that you're posting this shit on a forum thread first? Coward.
You could've posted that on a whole lot of threads before this one, what made you to decide to get all concerned just now?
