You don't even need high tech to make scam news. A German public channel once made a fake documentary that was after like half an hour "April fool's" to show how easy it is to look perfectly real. I think the long term solution is that people get used to that everything can be faked and that you need trusted channels directly to the source.

If you cannot find an endorsement. You can submit it to a scientific journal. Usually if they allow you to post it on arxiv you also can post it on your personal website. Note you might get rejected, but then you can use the feedback to improve the paper and submit it to another journal or same journal again. It is normal to get rejected at first.

Don't you need an bayesian approach for that?
