It's the obvious /pol/ posts from right wing/Russian farms, and mods blatantly allowing logposting. /b/ has always had mass porn. The captcha hurt things a lot too. Think I started browsing here in like, '07. Also >>937127446. The hack taking down 4chan and revealing that they secretly keep logs of what people have posted, especially for 4chan pass users, definitely didn't help the situation, but that's super recent, just the last few months.

At this point I just come for the porn and to be parasocial in the Twitch threads.

Weird that mods allow this. If you call him out he just calls you Eustace and tells you to take your meds.
