It's not even Madoka. It's just that the guy who is spamming shipping names is fucking CONSUMED with trying to harass people. You can't reason with him, you can't talk to him, and the only thing he does is act worse and worse.
You can tell by how for months now he is not replied to a single post directed at him. It's really insane.
He doesn't want to talk, he just wants to attack people. And even if you don't reply to him, he will just keep doing it.
He did the exact same thing in Is your order a rabbit? threads and he would just spam "kill yourself" at 100s of posts a thread, and even though no one replied to him, he kept doing that for almost a year until he realized that he's insanely more upset at him "ack" boogieman, and wants to spam crack names to try and harass that person.
He's now spamming the samething on the moe archives.
