There's a thread on the "zalgo" issue on GitHub where he's being a jerk. And he has a sizeable past history of jerkdom. Don't blame the victims that the well was poisoned, blame the jerk who poisoned it.
Do I really think he's a jerk? No, I think he's unwell. Previous headlines, lots of conspiracy theory posting recently, now this. He needs help.
Do I think this is an attack? We call other exploits attacks. The shoe fits. This was a deliberately hostile act.
