You never can tell how it was on the older days. I understand that your account was registered in 2017 which is old enough but I have this feeling that things were strick then. You might get yourself banned for talking good about altcoins and talking bad about bitcoin.
There was no time in the forum when someone will have gotten banned for talking bad about Bitcoin and hyping up altcoins as long as you kept the conversation constructive. There is a whole section for altcoins with different boards whereone can discuss freely about them.
Op, your account is a donator account. The admin will be very happy to make you recover this account only if you can prove that you own the account.
An account will not be unbanned caused it's a donator account without any reason to overturn the ban.
