I think I discovered something

I just discovered something and tested it and it worked I just want other people to test it and tell me if the same thing happens I HATE NSFW content and it rarely show for me, but past 2 days i was scrolling before going to sleep in a dark room and for some reason the NSFW content increased, it was like: normal reel, NSFW reel, another normal one, another NSFW one, so I just sat in a room with the lights on and covered the phone light sensor and guess what happened, yup exactly the NSFW content increased again, then I closed Instagram, waited few minutes and uncovered the sensor and opened Instagram again and my for you page went back to the normal content I hope you guys try this move and tell me what happen
