CLOAKING urls + hacked sites

Ok, we need to talk about this, some time ago I had noticed some sites that used this technique to climb the Google rankings and then redirected the content to advertisements, they normally ranked well for 1 month and were banned, not because of the technique but because of the redirection of announcement....

Today I come across a number of adult sites being ranked using the camouflage model.

Let's take a look at this url
https://hoanggiafarm.com/clara-nua-k.html
apparently without anything and without any link, as it is hidden from the common browser

if we open the
https://search.google.com/test/rich-results?hl=pt-brand put this url inside
will show some adult sites building backlinks, this is only because the browser's user agent is different from the user agent that the Google robot uses to index the pages.

Regarding hacked sites, I have a good idea that they are achieved via Logs that are easily sold today, with a good filtering tool it is possible to get the ftps and passwords...

I spoke to some owners of sites that appear in the links, either they didn't want to tell me the truth, or they simply said they didn't know how their urls appeared there... I find it hard to believe, but ok, then I'm going to throw the shit out on the fan and get my own answers, IF ANYONE wants to share an idea, call me on skype=blackmindrs

Interesting share. I have seen this a couple of times too

I already have a couple of weeks seeing the SERPs of adult keywords full of hacked sites (in several different languages). Some of them, recently created (at most a few weeks old) with no content and ranking for the top positions! WTF

For ex:
