Definitely disagree with the above fairly strongly re echo chambers not existing in online communities...the algorithms are going to adjust to user preferences in most cases. It even happens on here all the time with players being scapegoated. You do get outliers, like the whole world being pushed Andrew Tate for a few weeks to push engagement with him, even though he's fairly clearly a gowl. On the whole though, the daily consumption of the everyman is tailored to their interests - on Reddit, I see /r/soccer and /r/reddevils, I never come across /r/Liverpool. Anecdotally, it's fairly handy to see from the language people use over time too...you used to have lads in rural Ireland calling people "snowflakes" and the like because their YouTube was all Alex Jones and the "change my mind" prick. It's just naturally gonna happen over time - moreso with some platforms than others.
