It's also being griefed using obvious bots. Every 30 seconds or so the entire blade gets blocked out by a perfect checkerboard pattern done all at once. Or a perfect square will get whited out. Either spez is directing it or some reddit fanboy is defending his honor with a bot army
I consider r/place mods and spez to be the same group. I really just mean that it could be either an official action by reddit-affiliated person or could be bots run by someone who just dickrides spez, just trying to disclaim that obvious manipulation doesn't necessarily mean it's reddit's doing.
The placed pixels don't have a username associated with them. The bot drawings are done with obviously fake accounts, but each pixel still has an account.
I'm willing to bet the moderators of r/place aren't doing it/are glad it's taking this direction and/or the former mods of r/place were removed by cum-guzzling bootlicking admins who are now forcefully whitewashing reddit users' contributions.
