Some of the points in the OP are general suggestions that many forum users may have realized. But there's nothing wrong with reminding especially since there are a lot of new users who haven't noticed it yet.
7. You can carefully sign a message with your wallet address as well. This can help you prove ownership of your account in case you fall victim to account hacking, if you can sign a message with your wallet, then you can recover your forum account back.
I believe that sign message will help recover accounts in the event of a hack, but I don't know exactly how many bounty hunters are aware of it. Then, some old users may lose access to the wallet they used before so they will surely fail to sign message from that address. If this is the only way out there, then I'm sure any user who loses access to his wallet will also lose his account
[if hacked] specifically if he can't sign message.
