Would their clients know about this? Probably not. Probably global4t works on another proper name for their clients.
Let's think about a way to find out who are the clients, they probably would be very angry if they here about this.
P.S. to translatorpub: please remove the fake agency global4trans from your website!!! if you want to be a proper translators website!! They are still on the first page of the agency list.. and don't pay the translators. Thank you.
