Yeah you can lie to troll people but what I'm saying is that in this case it isn't. Damn near everybody that frequents myanimelist, r/anime and CR (three of if not the biggest three English speaking anime communities) know that Horriblesubs just rips off CR and Funi, so that "troll" catches out either people that are very new to anime or people that never pirate, which is hardly anybody. I think it's just a poor attempt to cover their asses. Almost nobody was fooled by this "troll" even for a second.
People who never pirate will not argue over what HS is. They won't even know HS.
Of course it's an excellent troll which is still delivering in this thread. And what do you mean nobody was fooled? How do you know that? And what makes you think one even needs to be fooled for a troll to be successful. Trolling involves a variety of tactics including misinformation. You could not be fooled and then go on ranting to everyone about how silly these guys are only to be told - No shirt, Captain Obvious, what did you expect?
Re: MAL. I sometimes visit MyAnimeList to see character listings and for spoilers in the forum section. The comments are of a terrible quality. But so far I've not seen anything about HS. I generally tend to avoid these sort of "reviews" as usually they have not much insight to deliver. Besides as Dao, says, "your favourite anime is sh-t".
Basically people will be insulted on HS and will still come back. Because they download that stuff.
It's not as bad as SomethingAwful where the forums are premium access, but it's still for suckers for punishment. And Dao does make it clear that he bans people too, but he can unban them, in all his magnanimity.
