@lololulu19 So many unconnected and disjointed thoughts in one post. I think you've also followed a couple of red herrings, but I'll try to stick to the main point.
Porn, in and of itself, is not obscene, at least not globally. If a court in Texas or Utah was to find that porn was obscene it would not have any effect on its standing in other countries. My understanding is that such a ruling would not even need to be recognised by other states. It's not unlike the situation surrounding marijuana in the US.
Given your numerous references to the US I think you've perhaps focussed your impressions around that and not fully appreciated the issue as viewed in other countries. Though something may be considered obscene somewhere that has very little bearing on whether or not it is able to be copyrighted.
You say that selling porn on the internet is illegal. Where exactly? Does that include The UK? Czech Republic? Netherlands? Germany? Brazil? How are all the porn studios, for instance in California, getting away with it if they're such an outrage to decency? I'm happy to read any citations you can provide to support that argument as it pertains to international copyright, and concede your point if they back up your assertions.
Your point about background music is certainly a valid one, at least here in the UK. I worked in a restaurant that got fined because we had a radio playing in the kitchen that could be heard by people on the phone. A bit petty, I think, but not something you can argue against. The police playing loud music is a new one on me, but that may be a US thing.
In fairness, I can see how you may have some to your conclusions about porn copyright, as I did do a quick Google search and found that the first 20 pages of results all seemed to be from US law firms and media. I read a few articles and the general consensus seems to be that nobody knows is its protected or not. It appears that the US courts at least are unprepared to come to a decision, and as such simply dismiss most cases, usually because the sheer number of cases would threaten to overwhelm the judicial system.
The point is that different countries, and indeed regions within some countries, have differing views on what is obscene as well as how respectful they are of copyrights. In Saudi Arabia all porn sites are apparently banned. China has acquired something of a reputation for ignoring copyrights and patents, at least when they are owned in other countries. None of these these things detract from the fact that the creator of a work, be that written, painted, filmed, played, or anything else which matches the definition, may have that work copyrighted. The only difference is how a particular legal system deals with a claim.
EDIT: Having re-read the original post in this topic, I think we've all gone off on red herrings. I believe @benignlulz was asking about non-porn trackers for TV shows and the like. I also believe his question was directed more to the idea that his ISP might find his internet activity suspicious and investigate, which I completely understand.
