How to hide a site?

Question

System administration

Good evening, even for which tag to write ... The crux of the matter, I am engaged in back-end development (now), there was no time and need to study the server part, but now I have, please explain in a simpler way how to hide the site from robots, and all that can block a site with obscene content (supervision and everything else). So that every passer-by without turning on the VPN could go to the site. There are special VPN servers where to store the site, or you can set it up on any server, to be honest, I don’t understand at all how it all happens, streams, who watches what, checks, and how to get around it all, well, preferably on a budget, the goal is not to buy, but understand. Thank you)

Answer 1

METHOD A
1) Well, let's say there is such a thing as "masking" the site.
Those. when entering the site - a site "about fish", and a simple user, incl. The RKN are freaking out that the site is clean, but the whole goodness lies in /folder/folder/folder/site filling which is masked in every possible way by htaccess
2) An external site is created (there can be a lot of them) and using the "1: 1" script, the site is taken from point 1
The script "1:1" is slightly complicated according to the scheme:

$content = file_get_contents('http://сайт с начинкой/папка/папка/папка/начинка сайта');
preg_match('....',$content,$match);
$replacement = array(
'это' => 'изменить на это',
'и это' => 'заменить на то',
'а это' => 'сделать таким');
echo str_replace(array_keys($replacement),array_values($replacement),$match[1]);

Well, there is a way B
bulletproof hosting somewhere in the darkness of Brazil
... but in any way, domains are blocked by RKN and registrars, so you will need to register domains too often and make mirrors, as rutorg is doing now

Answer 2

> So that every passer-by without turning on the VPN could go to the site
will not work.

Answer 3

Place your site on the TOR network, but the chances that you will not be interested is very small.
If you have legally prohibited content, then most likely you made a mistake with the resource.

Answer 4

the goal is not to buy, but to understand

Well, if so, then you need to start with the fact that the conditions
are mutually exclusive. Because the RKN and other regulatory bodies are also included in the set of "every passers-by."
There are ways to hide sites. And they are being used. Tor, I2P, hosting in Kuala Lumpur, domain zones in Mogadishu... But you need to know exactly what you are doing and (if it is actually illegal content) understand that one slip and a pative will come for you.

Answer 5

in RKN there are not robots, but Androids, you can’t hide from them,
and so - Cloudflare

So that every passer-by without turning on the VPN could go to the site

Answer 6

No way, then everyone would just hide it like that

Answer 7

Make access to the site closed by authorization. For example, no page will be opened until authorization passes. Robots and those without data will not be able to find out what the content on the site is. Like here: lurkmore.to/%D0%9B%D0%B5%D0%BF%D1%80%D0%B0

Answer 8

I do not understand, the question is about cloaking?
