that’s just not how recommendation algorithms work

I didn't say anything about how they work -- only that it shows you stuff it thinks you will like. You're disagreeing with that?

However, the largest part is collaboration based filtering of content. That means, our user is put in a group based on his other preferences, let’s assume nerdy tech stuff, and then is shown content that he has not liked yet but his group of peers has, meaning he could probably like it too.

Yes, based on other user patterns and how it categorizes him, it thinks he could probably like soft core porn too. That is, in fact, how it works. Glad we agree.

In other words - he’s not the one in fault here, YOU are

Please, could everyone here stop clicking on this stuff so that OP don’t have to be associated with your filthy behavior, thank you.

So it's perfectly realistic that everyone could be clicking on soft core porn to feed the algorithm these ideas, except that OP couldn't possibly be clicking on it, I guess for reasons?

Dude how could you write this hostile and condescending message when I actually made a specific point to highlight the exact point you're making ("It's not to say you're watching lots of soft core porn") in my message? If a little more succinctly.
