Can I put any name I want on the fivem server?

Hi, I want to change fivem server name to matrix rp. One of my friend told me that this name is registered and if you use this name the person who registered this name can report and your ip vps server will be blocked. I wanted to know if anyone can register their server name?
And that I didn’t see any server called Matrix rp in my country.
Will there be any problem if I use matrix rp?

you can use any name you want, unless one condition, they have the exact name copy righted, which 90% of servers do not, for example, there is about 50 different “CaliRP’s” one “big one” and the rest “small ones.”

Thankful <3
