Horror is a genre and its attributes do include disturbing. You do not have to find it disturbing. It is objectivly so, not subjectifly.
What you say and what others understand does not macth. horror does not equate violence. You seem to be disturbed by violence and because you think horror has to have violence you are proud that your horror is clean and pure.
I say again , save your time reporting stuff you do not like. There are adult tags that you cannot see or browse. It is hidden markers.
You claim to be developer. That means you work with computer for a living. You should unterstand scientific approach. Do it! Deactiveate your adult content in settings and test if you still see your supposed unlcear labeled adult stuff. But even there, what you think is adult stuff is probably different from stuff other people think is for adults only.
And to repeat it: no one cares if you think something is digusting. you can be offended by content ify ou like, but no one forces you to play content you do not like. And none gave you right to decide what is ok for others.
furthermore, if you are offended by such content, do not corrupt your mind by searching it out. That is like gay hater going to gay forum for gay bashing. do not be like this. People will insult you, belittle you and think you are a troll and bigot, fascist and intoleratn. And some of those accusations you will get might even be true.
