So you have to provide data matching from the banned account with the active account. and of course, the post is still on the forums. it hasn't been removed by the user, as @Xal0lex said.
Based on their own experience, global moderators do not consider links to posts from Ninjastic.space, as well as Loyce.club, as evidence. Posts that are used as evidence of any violation of the rules by users should be on the forum on a mandatory basis.
Wow, this is a new one for me, I had no idea. Any reason why they don't consider data from third party archive sites?
OP, have you tried reporting this case of ban evasion to the mods? If not, please try and do so. Maybe they just didn't see the post. Personally, I think the blockchain evidence gives enough proof.
