Is there anyway you can remove this from appearing on your server when players join?
This is a Gmod engine message and not a ULX/ULib one.
There is a work around though. Make sure any groups/users in your gmod/settings/users.txt are registered in ULib instead.
Once you've used ulx adduser for all the people in your gmod/settings/users.txt, remove them from that file.
This could cause problems for scripts that don't use IsAdmin, IsSuperadmin or IsUserGroup though and read from the gmod users.txt file directly.
Why would you want it removed though?
