If you're seeing ads while you're on a RHP site, it's probably coming from one of the ad companies by way of a nasty little cookie on your own computer. If you use AdBlock you'll find out who, but anyway it's easy enough to get rid of these things, I've just spent an afternoon doing it to 10 computers. 🙁 My cleaner of choice is Malwarebytes but there are plenty of others.
Russ has said if ads are seen by subscribers they definitely aren't coming from the site and you need to look at what's sitting on your home computer. There's nothing to be gained by switching browsers in my opinion, browsers only present the stuff that's served to them.
This comes up fairly frequently from subscribers in site support.
Each and every time it is malware, unfortunately.

edit : This does make me wonder how many non-subs get junk adverts when using the site that do not even originate from here...it certainly would explain all the red herring claims of seeing inappropriate ads over the years.
