Why when you see a single video it spreads your entire FYP

This is genuely gonna piss me the fuck off, WHY AM I SEEING RUSSIAN VIDEOS EVEN THOUGH THEY’RE MY FUCKING ENEMY, IMPRESS NOT INTERESTED LIKE 15 TIMES AND REFRESHED MY FUCKING FYP AND STILL GIVES FUCKING SAME ASS LAME VIDEOS

Even worse my brother saw one vid of someone vomiting, like experiment or some hantavirus shit, then after he sees one, he sees 50 of them, so wtf bruv?

Even when I like ONE single teeny tiny video, It multiplies by quintillion times
