You broke the site guidelines here. Would you mind reviewing https://news.ycombinator.com/newsguidelines.html? Note that they ask people not to post insinuations about astroturfing or shilling.
I know that's not a perfect answer, but it's pretty much all we have, and the approach does have one major advantage: it doesn't need to care how veiled an ad is, or if it's an ad at all.
I'm not as optimistic about thinking skills, because manipulation techniques seem to work anyhow. But barring actual evidence of abuse, I think we mostly can only try to get better at countering false or distorted information with more correct information.
Your comment is great without that first bit.
