My hashed IPV4 was published by an administrator on an anonymous imageboard (EU country)
<p>some days ago it on an anonymous imageboard it was opened by an administrator a thread with a .png showing all my posts on that website, and each posts had my hashed ipv4 attached to it.
Since i discovered that decrypting hash ipv4 is a walk in the park (less than 30 seconds on a normal consumer computer according to this research: <a href="https://dl.gi.de/handle/20.500.12116/16294" rel="nofollow noreferrer">https://dl.gi.de/handle/20.500.12116/16294</a> )
i'm here to ask you if i can start a legal cause against the admin of the website. I live in an European Union state so i should follow GDPR laws right?
The thread of which i speak it was also filled with threats and similar things, over 400 replies in total. </p>

<p>Thank you. </p>

<p>Generally, if you have a GDPR issue, it should be reported to your local <a href="https://edpb.europa.eu/about-edpb/board/members_en" rel="nofollow noreferrer">Data Protection</a> authority. </p>

<p>However, an attacker would have to: transcribe the hash from the image; attempt to reverse the hash (unless you have actually done that yourself, you are only guessing that the hash might be easily reversible). Having done that they have an IP address, which although PII, won't be readily traceable to an individual. Then when they have done all that, they know the name of someone who posted something on a bulletin board.</p>

<p>So, although there maybe a GDPR issue there, it's probably too trivial for anyone to worry about.</p>
