If there's one thing shitposters can be credited for, it's dedication. DM threads have been a thing on /a/ for at least a decade, and in all that time there were a few trolls here and there (it wouldn't be 4chan otherwise), but never as bad as it's been recently. The anime premiered last year, they've been at it non-stop even after season 1 ended, and they'll keep at it during season 2 and possibly after that too.

Sure, their narrative is always the exact same ("it's boring", "characters are ugly", "it's westoid shit", etc), they're not making that much of an effort to be subtle (though retards take their bait anyway so they don't even need to)... but they're certainly dedicated, I'll give them that.
