Actually, it can. It's Machine Learning - it can shift and adjust its own database based upon determinations made by other entries in that database.
As I said - hello Skynet.

I have yet to see(or read about) a piece of publicly used software used on current machines that learns new things by itself.
As far as I know Machine Learning is term used when u write a software that triggers its events based on conditions that used to happened in a repetitive time interval, like user changing its phone from silent to loud every day in 5 o'clock, the software if allowed by the user will remember the time frames and will change it for him.
Or it can remember a whole set of interactions and conditions; every time you are on the highway with your phone (location on) , probably going to work and someone calls you reject almost every call - and most of the times you immediately respond with a message; Your phone can open "Write a message" to the rejected caller by it self.
This sounds cool and smart but your phone repeats a decision, it is not making it by it self. You need to make it first and repeat its outcome a number of times in order the device to mimic you. It learns what you do it doesn't learn why you do it . And it certainty doesn't learn what the consequences/effects of your actions will be, like your boss getting annoyed for not answering the phone.
This is not learning this is repeating of previous repetitive interactions from the user, they are all based of sets of "If" and "Else if" in the code, there is nothing intelligent about them. The Computers could have done this same thing decades ago, your phone works on the same way as computers worked 50 years ago, this features are on now because of all the exes power and memory that the devices have.
Google has done immense research to make computing smarter and more human like, but its still the same thing , just remembering your habits and preferences and offering them back to you.
Its nothing smarter than the script on these boards when checking your text before setting it in preview, going: "if line brakes group has more than 2 - delete all and add 2".
If Machine Learning was actually Machine Learning - U wouldn't wait for those updates on your apps written by a human to download from some server : your phone would have updated/upgraded them internally.
And by the way; databases just hold information in tables, software reads, writes and deletes that information and that was apparently the whole purpose of databases, so that shifting and adjusting was done from beginning of their time to them.
The problems why machines cant learn or be intelligent lies in the problem. They just cant find a problem, with anything! According to them everything everywhere is OK. Its not even awesome its just plain ok. They don't know if an occurrence will be a problem unless we tell them it is or it is going to be.
They just cant find a new problem.
And don't get the wrong idea, when an software says back "ERROR" its actually a specially written software tracking the processes on the software on which the error happened.
The way our brain works is just predicting the future; all day long watching and smelling and touching: and trying to figure out what is going to happen if you cross the street or if you eat a candy or if you insult someone. It compares all current available data with past experiences and acts to set itself to be in the most comfortable situation possible in any outcome.
Machines from now just don't have access to such vast "current" and "experienced" data and the power to go fast trough that data as brains do. And they have very hard time valuing that data as currently necessary or irrelevant.
We will know when a computer gets intelligent; It will ask "What is that?" and will probably ask to sleep an hour after that to process and value all the new information. If its not asking question its not smart and its definitely not learning.
But what do I know. I just write software 8 hours a day. Maybe you are right - Skynet is on the rise.
So No! Im strongly convinced that Riot doesn't have a system that can find a newly ** (new for it) occurring toxic behavior manifested by a human and suggest action by itself.
The system doesn't know what the comments mean in a report, just does what a human tells it to do if it finds them.
The "Learning" part probably just refers to part of the finalizing process of a case: it does the background checks on the reported summoner and if quota is met builds a case. It then "grades" his current case based on previous outcomes on which staff passed judgement on to him , or the next most similar case to his. If the grade is concerning staff its notified that case needs judgement.
And stuff judges it - then if the system "Learns" **his case for future comparison for similar behaviors.
So basically you report him for "Negative Attitude", he doesn't say anything in chat except "gg" = False report. Just because all previous "Negative Attitude" with no chating back from the reported one are "Pardon".
