When visiting the https://portableapps.com/news site while NOT being logged in, the navigation buttons seem to sometimes contain spam links.
Example from the source of page 1:
<li class="pager-item"><a title="Go to page 2" href="/news/2008-12-18_-_karoseri-truck-jakarta.blogspot.com/2016/05/info-harga-pembuatan-truck-bak-besi.html_portable_3.0?page=1">2</a></li>
<li class="pager-item"><a title="Go to page 3" href="/news/2008-12-18_-_karoseri-truck-jakarta.blogspot.com/2016/05/info-harga-pembuatan-truck-bak-besi.html_portable_3.0?page=2">3</a></li>
<li class="pager-item"><a title="Go to page 4" href="/news/2008-12-18_-_karoseri-truck-jakarta.blogspot.com/2016/05/info-harga-pembuatan-truck-bak-besi.html_portable_3.0?page=3">4</a></li>
<li class="pager-item"><a title="Go to page 5" href="/news/2008-12-18_-_karoseri-truck-jakarta.blogspot.com/2016/05/info-harga-pembuatan-truck-bak-besi.html_portable_3.0?page=4">5</a></li>
<li class="pager-next"><a title="Go to next page" href="/news/2008-12-18_-_karoseri-truck-jakarta.blogspot.com/2016/05/info-harga-pembuatan-truck-bak-besi.html_portable_3.0?page=1">next ›</a></li>
<li class="pager-last last"><a title="Go to last page" href="/news/2008-12-18_-_karoseri-truck-jakarta.blogspot.com/2016/05/info-harga-pembuatan-truck-bak-besi.html_portable_3.0?page=4">last »</a></li>
or page 3:

It looks like these are old spam entries from long ago that have been purged yet somehow survived in the navigation links. The strange thing is that they are not always the same, even for the same page, and sometimes there are even none at all (navigation normal).
What could that be and is it harmful, maybe?
It was determined back in 2017 that it was my system doing this:
JTH: "No Such Links - There are no such links within our pages themselves. There could be something on your system or network. Or an extension in your browser."
And, it is still doing this - even search engine like DuckDuckGo can see it.
See my old post for reference:
Phishing-like URLs on PAc's News Pages

It's an odd Drupal bug that lets anyone pollute the cache of pager links in the Views module via incoming links to the pages. It has no effect on anything. You can click through and the links work exactly as expected. I just cleared the cache, so you'll see it's clean again.
Sometimes, the impossible can become possible, if you're awesome!
Interesting, so, it's the content delivery framework (Drupal PHP) but has no influence on actual navigation.
Thanks for clarifying, just wanted to make sure.
