Why was the site blocked by Roskomnadzor?

Question

Layout

I could not really decide on the tags, perhaps the chosen one is suitable.
The bottom line is that today this error began to appear at the entrance, I checked 833991
-URL-on on eais.rkn.gov.ru dated 08.11.2019 Roskomnadzor is limited to the site
Immediately and completely, and still no information. Complaints from the host did not come. Technically, this is a forum, of course, that anything can be posted, but there is moderation by itself.
Before that, too, everything happened, but there is always a preliminary complaint and the site shows what exactly and for what was blocked.

Answer 2

Can be flex

<div class="wrapper">
    <div class="content"></div>
    <div class="spacer"></div> <!-- пустой div -->
    <div class="spacer"></div> <!-- пустой div -->
    <div class="content"></div>
    <div class="content"></div>
    <div class="spacer"></div> <!-- пустой div -->
</div>

.wrapper {
    display: flex;
    flex-wrap: wrap;
}

.wrapper>div {
    width: 50%
}

for mobiles just .spacer {display: none} and .wrapper {flex-direction: column}, well, the width is 100%

Answer 3

Sometimes the RKN just sends a block notification without much explanation. Sometimes it also removes the lock after a while. They don't have any logic.
A letter arrives "Roskomnadzor informs" blablabla that the following IP / URL is entered in the registry and they do not specifically report why and how.

Answer 4

Roskomnadzor always writes a letter to [email protected] with prohibited content
