I think you're confusing two things, 4chan are trolls they target people with reactions anything from Taiwan is number 1 in Chinese forums, Harambe phone calls to zoos, etc.
Trolling is based off reaction example the reason Pepe got big in 2016 during the election because Clinton's team published an entire article on their front page talking about how its a racist symbol......the end result they kept sending in those pictures to the DNC.
I remember the Victims of Communism memorial got 100s of phone calls and faxes because one of co-founders of the US chapter said something about one of their message boards.
They target anyone who they think will be loud enough to get noticed, why do you think they kept taking down Shia LaBeouf's flag?
