I think you might be mistaking trixehh with someone else. I can think of 2 people this recently happened with, and neither was the OP.
While I dont recall him ever rep trading, I do remember that he was the guy who got his first ~38 rep exclusively from reposts (literally), and I used to call him out on it every time. That actually can be confirmed here:

Although, I will give him credit, ever since I got on his ass every thread, he has ceased with the constant repost extravaganza to farm rep.
Though it was prob a bad idea to both flame, and admit to breaking the site rules, all in 1 thread. Even if it was (allegedly) your friend, account sharing is against the rules, and really, why would your "friend" go out of his way to try to get you banned. Sounds fishy to me honestly.
