I'm a little confused because the hacker and ddoser seems completely separate from scratch and the people targeting you in the third pub.
From what I've read of your story, it seems like the hacker / ddoser are the people are hard targeting you through two separate occasions. But what you told in your story it doesn't seem that scratch is directly involved with cheating or ddosing as a way to attack you.
I'm not sure why more people here aren't more alarmed or concerned about scratch continuing to "follow" you around servers and target you. I don't think its nearly as sinister as his previous behavior but it seems like he still has you as a target so I'm surprised with how many people are defending him here. With his history of targeting you, this might be more evidence for his seeming fixation on you and could constitute continual harassment.
At the same time, taking his behavior here by itself, its little more than just trolling. From the chat, I don't any directed slurs or actual harassment. I'm hesitant on thinking this warrants a "permaban from every tf2 platform" because in the end, he's focusing you in a public video game.
I think the main thing that most people here agree on is that what scratch is not provably or directly tied to the ddosing/cheating and taken in isolation, he's trolling. So permaban across everything seems extreme.
How The Fuck Is This TransPhobia
While I agree that its dumb steph brings that up as a defense/accusation, nowhere in the original post did steph mention transphobia. I don't think thats her point. Then again, her main point is kinda misguided
