Trademark liability insurance when buying a domain - what are the risks?

Question

Domain name market

I want to buy a domain with the name of the residential complex in which I live.
I will organize a forum for communication of the residents of the house there.
nic.ru offers this service:

inexpensive, of course, but what does it actually give? insurance if the LCD sues me for using their name?
although in fact they most likely did not register the name of the residential complex as a trademark? or I don't understand something?
and then insurance in general is essentially called one at a time - but in fact it is written:

there is no sense?
And how do you check for a registered trademark? For example here: https://onlinepatent.ru/trademarks/ ? But there, when I call my LCD, it is displayeda bunch of trademarks - and with the same name, but without the prefix lcd and there is no developer office

Answer 1

marketing bullshit.
