Int. Feeding is still not punished

why is int. feeding still not banable? its a report-reason, but there are so many accounts arroung feeding their ass off and still not punished. i have an account (not this one) were is just start feeding if i think the game is not winable,....and the aco%%%% is since mid season 7 NOT PUNISHED. i didnt even get a single warning or what so ever. but there are other account were i get instantly banned for 7days if flame someone. are there real people behind the ban-system or is it just a bad-language filter?
