Why are 4chan traffic numbers falling so drastically?
Take a look for yourself.
What sites link to 4chan.org?
1. Exclusive: YouTube Music Vlogger Mistaken for Oregon Shooter Speaks Out
2. /r/8chan (what the fuck)
3. A screenshot with a 4chan tab uploaded to imgur by the e-sports player Doublelift (never mind, I feel like there's probably some sort of sample size problem here...)
4. A report by MSN Germany about people shopping ducks onto ISIS heads.
5. An announcement of a discussion between moot and hiroyuki to be hosted on Nicovideo circa 2011, about social media.
Shitposting countries got rangebanned from some boards which equals a lot less bans which also means a lot less "new" IPs visiting the site.
