@thats what I thought as well, I would have run away far from the site, if it supposedly infected my PC, let alone going back there and posting comments upon comments. 
I am amazed at the audacity of this moronic ingrate. First he attacks, and then he defends himself ridiculously ("I've 4-5 roommates using sajha. So, 4-5 people couldn't afford to buy their own laptop, how much does it cost, less than 300 bucks"). Then he is concerned about the privacy of his other roommates(which undoubtedly are several other iterations of himself). To add more, he allegedly filed a case, case for what? for a computer thats porn ridden and infected? Somehow if his inbox is hacked, scammers don't make threats to contacts within, they literally beg for money or find reasons to leech any financial benefits off them. I'm pretty much sure, this dumbo must have made some threats through email, he knew he's in trouble and if authorities must have knocked his door, he blatantly put blame on the site that he regular visited. He went one step ahead by creating a thread. Now, he would show it to authories(IF THERE IS ANY SUCH GAME going on, IF) to validate his intent. 
Usually, thats how  these insolent dumb[Disallowed String for - bad word]s react when their real identity is compromised. Anyone read news of similar contexts in past months, they send nude pictures, threats to people and when they're busted, they say their phone or email is hacked, but later on how they're caught and proven guilty. This guy is nothing but a waste of time, he wasted every one of us' time here. And he's the culprit himself, no one.
