How can it be ban evading when otto_diesel's message predates that of the banned user

It doesn't matter which sockpuppet gets banned first, it would still be ban evasion if both accounts belong to the same person.
Also the posting of an identical wallet alone, by itself, is definitely not a robust way of ascertaining whether 2 accounts are the same person,
if that were the case, someone could make an account right now, post one of your wallets and try to get you banned; you and all the intelligent members of this forum would agree, this is not a smart way to jump to conclusions about anything...
That's not what happened there. If someone wanted to frame otto_diesel they wouldn't have posted the address in some obscure thread to wait nearly two years for marlboroza to find it. A more plausible excuse would be copy-pasta error but even that seems quite unlikely.
Sure moderators might not find this damning enough but given that a DT1 member is involved it would be nice to get theymos or Cryptios to take a look at IPs and whatnot.
