The site’s owner Hiroyuki Nisimura wrote in a post that “4chan can’t afford infrastructure costs, network fee, servers cost, CDN and etc, now”.
Nisimura says ads haven’t been effective enough to support the site, nor have subscriptions offering additional features. “We had tried to keep 4chan as is. But I failed. I am sincerely sorry. Parts of 4chan may have to close”
Three things could keep 4Chan alive. More subscriptions, include “much more” ads, or cut traffic to the site in half. This could be done by closing message boards, slowing down the site, or reducing the size of images that can be posted.
All this will mean an end to the site’s Wild West Culture. 4chan is the land of script kiddies, countless memes, racism, sexism, and otherwise purile discussions and Gamergate which was about hassling women online.
While few people would miss the death of 4Chan, there is an element of “who the hell is able to make any money from the internet these days?” News sites are closing as advertising fails to make any money for anyone other than Google.
