Greetings,
Doxing attempts are illegal in many countries and should be handled by the platform where they happen.
For example for naval action it would be naval action game, naval action facebook and naval action forums. The screens your provided do not belong to Naval Action or Game Labs platforms, are not official and are not managed by Game Labs. By posting and being present on unofficial platform you are not protected by GL. If they have the official name in them its illegal. Please provide the links to the platform.
If you believe someone doxxed you on those platforms please report this to platform mods, then if they don't act to the platform, and if they don't act go to the local police.
For example if you were doxxed on unofficial discord or unofficial reddit you should first report the case to mods and file the complaint using the privacy help line of the platform (usually they have one). Most platforms take these cases very seriously and will ban the person who doxed you. If you want to continue this further, file the report to the police (USA and EU will most likely act on it). Posting private information is against the law in many countries.
Unfortunately we cannot help more as we are not even present in that discord and they are private to us. Some unofficial platforms are biased against the devs or a game and might not help you at all (in this case go directly to platform privacy violations channels).
We encourage users to use only official platforms like Game Labs forums as you are protected from doxing and we do not even allow posting private anonymous messages here.
