nobody user - user can't upload file

[become]

Hello

I created account with user123.
Then login to that account and add some domain.
As I see chown of the root vhost directory is "nobody" user
Problem is when I try to upload files with FTP to this directory. I can't do this.
I logged with user123 login.

After change owner of directory to user123 everything is ok.

Why ?
