Since we had a few confusions about some members not reading that certain topics are already reserved, maybe we can add a few lines to your OP to require some sort of application procedure, where interested translators are required to leave a reply in your topic to reserve a certain topic and they can only start to translate it, if their application is officially approved by GazetaBitcoin.
Just an idea how it could look like:
#reserve
I would like to reserve a topic for a translation
Bitcointalk Account: xxx
Language: xxx
Requested topic: xxx
Maybe we can add more application details but for now, it should be sufficient.
Of course it's up to you how / if such an application process will be added but after our incident, it came to my mind to require a #reserve post to get officially accepted for translating certain topics and to avoid future incidents.
