I've had a similar experience. I've been trying to quit porn off and on for a while now. At one time I considered myself as practicing NoFap. I consumed all the introductory content you first come across, abstained from masterbating for varying stretches of time, and visited the subreddit fairly regularly.
I would say overusing porn can for sure have downsides, and abstaining from masterbating for a short time could help with getting out of the habit of using porn. The community just gets so much more weird and cringe from there, not to mention the violence that is fostered there which I wasn't aware of. Maybe the forum was more hardline.
That video looks interesting too, thanks for sharing!
I'm having the exact same problem.
