Is hosting obligated to remove fake and hacker sites?

Question

Phishing

Good afternoon. Recently, I have been getting messages like
this very often: "Hey, my friend can not add, add him wants to trade
steamcommnulity.com/id/Nikolya ". Messages are received on
the Steam digital distribution service. People who send messages of this nature intend to
gain access to someone else's account through their fake sites like "steamcormuniti.com" or
"steamcommnulity.com" (in turn, the official site has the following address
"steamcommunity.com"). Thus, account holders suffer huge financial losses.
There are many similar sites, and as practice has shown, almost all sites are located on the same hosting. In this regard, I wrote a complaint to this hosting, asking them to somehow track the registration of similar domains.
The question is: are they obliged to take action? (website blocking, etc.)
By the way, here are screenshots of some messages:

Answer 1

Yes, it depends on the rules, in fact, hosting. Well, partly - from the laws of the country under whose jurisdiction the hosting company is located.
There is a whole class of so-called "bull-proof" hosting companies that simply ignore any letters of complaints and petitions against their clients. There are even several "levels" of such hosting, at the highest (high | low?) even child porn, even calls for the assassination of the president, they won't delete anything.

Answer 2

Depending on what is written in the user agreement.

Answer 3

You can still come in from the other side, write an abuse to the registrar to block the domain.

Answer 4

One is hosted on reg.ru, the second on timeweb.ru
Should be covered if you write to hosters that they are trying to steal passwords from their networks.
Phishing is expressly prohibited.
