hi,
It could be that your account has been linked with the account of someone else that has been banned (ban evasion isn't allowed).
The link could be a and ETH address you share or a twitter handle.
it could also be that you have plagiarized
Give it a few hours / day and someone will bring you the reason behind the ban.
Bans are almost always justified.
it's true, the account is linked to the account that I made in 2017 but the account has been banned, this is unfair, if the issue of ETH address or social media is a reason for the ban, because it is not possible I have to fake the identity of social media accounts
