Oxide server mod in "Community" server list

Good day. I am interested in this question. Why is the server with the mod oxide, are displayed in the search community. And how this is achieved, you can?

It can be done but if the devs catch you your server IP is permanently blacklisted. So I suggest not looking up how to do it.

I understand.
Such servers more than 50 pieces, and I do not see anything they would get banned. I can give ip, Such servers more than 50 pieces, and I do not see anything they would get banned. I can give ip
p/s
I have this situation exasperated, I can not find a normal server without mods
