Algorithms MUST go from the general to the specific (particular). But it is IMPOSSIBLE for the brightest, most positive-minded person to do this safely. In fact this has been a point of logic for centuries. You could use data along certain lines to improve xHamster, but even the most talented interpreters could not anticipate all the twists and turns of possibilities. Until recently I was an active participant in a news organization quite happy with my contribultions—untll well-intended algorithms became so censorious that finally I said goodbye. No one INTENDED this to happen, but it was impossible for me (and others as well) to continue. I had six or seven THOUSAND "likes" from people, but algorithms were looking for negatives in such a way the positives became increasingly entangled. (It is actually a common background by which horror movies have long been created!) The problem is, the entire world is represented by the "general" and you are attempting to "tame" what you present. I'm older and I have taught business communications university courses in years past. I am intending this to CAUTION you; nothing more. Please TRY to avoid algorithms for all value judgments. Even the most biased human is less dangerous than the very best attempt at a blind algorithmic judgment. BE CAREFUL!!! Thank you.
