nexus868... here's what I'm guessing might be going on, noting that this is speculation, and that I'm not clear exactly what it is you're seeing.
As I understand your post, you are in Italy, and you're not seeing your sites ranking as expected on various international Google sites you try. It may
also be, on some Google ccTLDs, that results for your queries are completely blocked, but I'm not sure about that.
First, if you haven't seen it already, look at this recent WebmasterWorld thread where we are discussing Google's new way of localizing international serps. It might have a lot to do with what's going on
for anyone checking international results. Country-specific Google sites now all searching my local country Oct 27, 2017 https://www.webmasterworld.com/google/4874425.htm [webmasterworld.com]
It turns out that Google's country specific serps are no longer localized by the Google ccTLD of the target country site you're searching. Instead, they're determined by the location of the searcher. This may be both good news and bad news for you. If you, in Italy, are not seeing the country-specific results you'd expected to see, say in the UK, you might be able to change that by resetting your
search settings. See the referenced Google blog post. Note that you will need to be signed in to Google for search settings to be retained by Google's cookies.
On the other hand, for results from Indonesia, along with other countries where your niche is banned, there's likely an additional factor. Note near the end of the above thread, I post that Google may have made this change because it...
...would make it easier for Google to comply with requests from foreign governments to make country-specific serp changes.
. From various comments I'm seeing on the web and on this forum, I'm guessing that Google is now needing to deal with a lot of different national laws, so it must deal with results as seen in the countries where those laws are in place.
I don't know precisely what you're seeing via the posted shortened link of the serps for your
"main NSFW keyword", but here in the US it's intercepted by a Google URL Shortener advice page stating that...
...this goo.gl shortlink has been disabled. It was found to be violating our Terms of Service. Click here and here for more information about our terms and policies respectively.
Note, btw, that WebmasterWorld doesn't allow posting of specifics... including serps that identify sites, search queries, etc... and particularly not NSFW terms. As mod, I allowed the shortened link only because it wasn't returning identifiable serps.
I don't know whether you're seeing the same link shortener page I'm seeing, nor do I have any idea what set of laws or Google policies the query might be breaking. Please provide further detail and thoughts, but please do not post specific search terms, site names, or urls.
On any international Google ccTLDs where you are seeing serps pages but your results have changed, try changing your search settings... and let us know if that helps.
