I use a laptop and get ads. They are always in one area near the top of the page and are always presented as a narrow banner that goes across the page. Sometimes they are animated and sometimes not. As far as I can tell they do not ever cover or block the site content.
If you are getting something other than that I suspect you may need to scan your computer for viruses and malware. I think others have had pop-up ads and other similar problems in the past and after scanning and removing malware the problem ended.
Russ, are the narrow 'strip' ads that I described the only ads that are part of the rhp web site pages? It seems like this was discussed in earlier times and that was the case?
As I understand it, subscribers do not ever see any ads, and non-subscribers get only the narrow strip-type ads I have described. If anyone gets other ads it is a good chance your computer is infected with some type of malware.
