#the goal being that by doing so my feed is instantly populated with a regular feed of content related to my interest

>normal tumblr guy exists

>follows wide assortment of blogs relevant to their interests

>becomes mutuals with many different users, some normal, some insane

>eventually gets deleted for posting a little too close to the sun

>remakes, can't remember everyone they followed, only re-follows the urls he can recall

>they are invariably the most obnoxious, politically extreme, and terminally online of their former mutuals

>their feed becomes more obnoxious, politically extreme, and terminally online as a result

>the content they reblog reflects this

>repeat cycle a few more times, each time following fewer blogs related to their actual interests and more blogs related to politics and extremism

>normal guy is now, for all intents and purposes, a political extremist

Many such cases!
