We are in the era of high technology and I think this can not eliminate the fake news that we have as those people who spread fake news will find any loop holes in the system. It's a business and money can buy everything.
It's all about money, fake news is one of those sources to attract more readers, even we try to eliminate those who are working behind this type of business they will still find the ways to proceed and create new items, if money works, any system can be overcome, there's no such limitations as
the sources over the net is really unlimited for people who loves to explore.
You right, news like that will always be there because the media is looking for money from it? there will always be an interest, so hoax and fake news will continue to be made, of course with a specific purpose, how strong even in eliminating such news, they will always be there
