Where to get phorx ledevin etc. The undercover accounts?

Hi, I always see in the videos from ledevin or whatever, that they have a lot of 2 accounts in Minecraft and I wanted to ask where they came from?

because they always have so many and I don't think the Minecraft YouTubers that everyone bought?
I also needed some for my server (leFynni.citybuild.one) maybe. Can answer so.

They are always there with their main account, they just nodded. Better said with / nick. The videos are all fake

Oh honestly because with a video ledevin said: oh my mc is supported and now I have to log in again with the Alt account…

I don't know ledevin yet, but Abge and Phorx. And with Abge there was always the same account duplicator in 3 videos in a month

Ok thanks
