Hello community, actually I've seen on other website, haven't tested by myself but some people wrote it works.
This is worth a try, according to the EU laws, you can ask the host to remove your personal information. (Like EAC who's operating in Finland :)) )
Go to EASY.AC
Go to support and appeal the ban for Rust.
Login and fill everything.
At the reason, state that you want them to send you all the data they have about you, and then to remove it from their system.
OPTIONAL: You can tell them to delete your personal data under the rule "GDPR" --> https://gdpr-info.eu/
After 24h they should reply with confirmation.
I've seen somebody tried it and got a reply from EAC says they deleted the information including HWID
This should work with any EAC protected game, but Rust devs are known for manually banning, so they may have a second shitlist aside from EAC.
Thanks to CZERO
